what is 2 1/2 divided by 1/3
The value of the 2¹/₂ divided by 1/3 is equal to 15/2, or 7¹/₂
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.
So, we can rewrite the expression as:
2¹/₃ ÷ 1/3 = (5/2) ÷ (1/3)
Now, we multiply the first fraction by the reciprocal of the second fraction:
(5/2) ÷ (1/3) = (5/2) × (3/1)
Multiplying the numerators and denominators, we get:
(5 × 3) ÷ (2 × 1) = 15/2
Therefore, 2¹/₂ divided by 1/3 is equal to 15/2, or 7¹/₂.

The sum of 3 consecutive odd numbers is 51 what is the second number in the sequence
Answer:
The second number in the sequence is 17.
Step-by-step explanation:
Let the three consecutive odd numbers be 2x-1,2x+1 and 2x+3
As per the question, the sum of the 2 odd numbers is 51.
So forming the relevant equation:
(2x-1) + (2x+1) + (2x+3) = 51
=> 6x + 3 = 51
=> 6x = 51-3 = 48
=> x = 48/6 = 8
Calculating the individual numbers:
2x-1 = 2*8 -1 = 16 - 1 = 152x+1 = 2*8+1 = 16 + 1 = 172x+3 = 2*8 +3 = 16 + 3 = 19So the consecutive odd numbers are 15,17,19 and the second number in the sequence is 17.

Theo needs to measure 3/4 cups of water. He has a 1/8 cup measuring cup. How many 1/8 cups are in 3/4 cup?
The number of 1/8 cups in 3/4 cup is given by the equation A = 6 cups
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of cups be represented as A
Now , the equation will be
The amount of the bigger cup = 3/4
The size of the measuring cup = 1/8
So , the number of cups A = amount of the bigger cup / size of the measuring cup
Substituting the values in the equation , we get
The number of cups A = ( 3/4 ) / ( 1/8 )
On simplifying the equation , we get
The number of cups A = ( 3/4 ) x 8
The number of cups A = 3 x 2
The number of cups A = 6 cups
Therefore , the value of A is 6 cups
Hence , the number of cups is 6 cups

Marvin is trying to finish 1/2 of his test every 2/3 hour. How many hours will it take Marvin to complete his whole test
It will take Marvin 4/3 hours to complete his entire test.
Time taken to complete 1/2 of test = 2/3 hours
The total fraction of the test can be represented as 1
Therefore,
If 1/2 of test = 2/3 hours
1 of test = x
We can solve for x using cross multiplication :
1/2x = 2/3
Multiply both sides by 2 to isolate x
(1/2x × 2) = (2/3 × 2)
x = 4/3 hours
The number of hours it will take to complete the whole test is 4/3 hours

There are 21 students in one class and 19 in another. The lab has 34 computers. How many students will need to share a computer when both classes are in the lab at the same time ?
A total of 6 students from the combined classes of 21 and 19 students will need to share computers in a lab with 34 computers available.
The question involves determining how many students will need to share a computer when both classes with 21 and 19 students, respectively, are in a computer lab with 34 computers at the same time. To solve this, you can add the number of students in both classes to get the total number of students, and then subtract the number of available computers to find out how many students will need to share.
Adding the two classes together, 21 + 19, we get a total of 40 students. Since there are 34 computers, we subtract this from the total number of students: 40 - 34 equals 6. Therefore, 6 students will need to share a computer.

If h(x) = −2x − 10, find h(−4). −2 −18 −3 −16
Answer:
The correct option is (a) i.e.
h(-4) = -2
Step-by-step explanation:
The mathematical expression is given as :
[tex]h(x)=-2x-10[/tex]......(1)
Where
h(x) is dependent on x
We need to find the value of h(x) at x = -4 . Putting the value of x in equation (1) we get :
[tex]h(-4)=-2(-4)-10[/tex]
[tex]h(-4)=8-10[/tex]
h(-4) = -2
The value of h(-4) is -2. So, the correct option is (a). Hence, this is the required solution.
