Explain how to check multiplication using addition and division ñ. Include an example in your explanation.
Multiplication can be checked using division and addition by following these steps: multiply two numbers, divide the product by one of the numbers used in multiplication (correct multiplication gives the other number), and validate multiplication using repeated addition (adding one of the numbers as many times as the value of the other number).
Explanation:You can check multiplication using addition and division by following these steps:
Let's take an example of multiplying two numbers, say, 4 and 5, which equals 20. Then, divide the product with one of the multiplier numbers that you used for multiplication. For instance, when you divide 20 (the product of 4 and 5) by 4, you'll get 5. If you get the other number (that you multiplied with at first), then your multiplication was correct. You can also verify multiplication by using repeated addition. In our example, if you add 4 five times: 4 + 4 + 4 + 4 + 4, you'll get 20, which is the same result as the multiplication problem.Learn more about Checking Multiplication here:

During a checkers game, there are 16 pieces left. The ratio of black to red is 3 : 5. How many black pieces are on the board?
To find the number of black pieces in a checkers game with a black to red ratio of 3:5 and a total of 16 pieces, you can form and solve an algebraic equation, resulting in 6 black pieces.
To determine the number of black pieces in a checkers game when given the total pieces and the ratio of black to red pieces, you can set up a proportion. With a total of 16 pieces and a ratio of 3:5 black to red, we can use algebra to find the answer. Let's denote the number of black pieces as 'b' and the number of red pieces as 'r'.
According to the ratio, we have b/r = 3/5. We also know that b + r = 16 because the total number of pieces is 16. By cross-multiplying the ratio, we get 5b = 3r. We can substitute r with 16 - b in this equation (from our total) to get: 5b = 3(16 - b).
Solving this, we have: 5b = 48 - 3b which simplifies to 8b = 48. Thus, b = 48/8, which means there are 6 black pieces on the board.

The bicycle rental shop charges a fee of $6 It also charges $3 per hour that the bike is out if you rented the bike for h hours what expression describes the cost of renting the bicycle
Final answer:
The cost of renting a bicycle is expressed as $6 + $3h, which includes a flat fee of $6 plus $3 for each hour the bike is rented.
Explanation:
The cost of renting a bicycle from the rental shop can be described by an algebraic expression that takes into account both the flat fee and the hourly charge. To calculate the total cost, you multiply the number of hours the bike is rented (h) by the hourly rate ($3) and then add the flat fee ($6).
Step-by-Step Calculation
Determine the hourly rental rate: $3 per hour.
Multiply the hourly rate by the number of hours the bike is rented: $3 x h.
Add the flat fee to the hourly charge: $6 + ($3 x h).
Therefore, the expression that describes the cost of renting the bicycle is $6 + $3h.

Compare the minimum,maximum,and median of the box plot
A box plot graphically represents a dataset with five key points, including the minimum, median, and maximum values, which provide insights into the dataset's range, central tendency, and distribution.
A box plot, or box-and-whisker plot, is a graphical representation of a dataset that includes five key data points: the minimum value, the first quartile (Q1), the median (Q2 or second quartile), the third quartile (Q3), and the maximum value.
The minimum and maximum values determine the ends of the whiskers on the plot and give a visual representation of the range of the dataset. The first and third quartiles represent the edges of the box and span the interquartile range (IQR), which encompasses the middle 50% of the data. The median is represented by a line within the box and indicates the central value of the dataset.
When comparing the minimum, maximum, and median values on a box plot, we are essentially examining the range of the data, its central tendency, and its spread. The position of the median within the box can indicate skewness in the data, with a median closer to the lower quartile suggesting a right skew and a median closer to the upper quartile suggesting a left skew.

How many 3/4 are in 7/8
To determine how many 3/4 are in 7/8, you would divide the first fraction by the second, which involves multiplying 7/8 by the reciprocal of 3/4 (which is 4/3), resulting in approximately 1.17.
Explanation:To find out how many 3/4 are in 7/8, you have to divide 7/8 by 3/4. Division in fractions requires the multiplication of the first fraction by the reciprocal of the second fraction.
So, the reciprocal of 3/4 is 4/3. Now, you multiply 7/8 by 4/3 to get:
(7/8) * (4/3) = 7*4 / 8*3 = 28/24
Simplify the fraction 28/24 by dividing both numbers by their greatest common divisor, which is 4, resulting in the fraction 7/6.
So, there are 7/6, or about 1.17 times of 3/4 in 7/8.
