kenny has 9 more comic books than bobbie. together they have 95 comic books. define a variable. then write an equation that could be used to find the number of comic books they each have.

Answers

Number of comic books Bobbie has - b

95 = (9 + b) + b

Since 95 is the total number of comic books both boys have, it is equal to both boys' books added together. However, since we don't know how many books Kenny has, and only that he has 9 more than Bobbie, we can define that as (9 + b), or nine more than b. Then, we add b again, because (9 + b) is the number of books Kenny has, and if we add that to the number of books Bobbie has, it will equal the total of 95 comic books.

3 3/4 Divided by 2 1/12

Answers

The required answer would be a fraction of 9/5 which is determined by 3 3/4 Divided by 2 1/12.

What is the fraction?

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

To determine the evaluation of 3 3/4 Divided by 2 1/12

⇒ 3 3/4 ÷ 2 1/12

Convert the mixed fractions into the Improper fraction, we get

⇒ 15/4 ÷ 25/12

Apply the Division operation, and we get

⇒ (15/4) / (25/12)

Reciprocal the terms of the denominator

⇒ (15/4) × (12/25)

⇒ 180/100

⇒ 18/10

⇒ 9/5

Therefore, the required evaluation of 3 3/4 Divided by 2 1/12 would be a fraction of 9/5.

First make the fractions into improper fractions.
So then it becomes
15/4 divided by 25/12.
Next do the KCF method (Keep.change. Flip)
Keep 15/4 the same and switch the numbers of 25 and twelve. Then multiply.
15/4 x 12/25= 180/100
Simplify.
So 3 3/4 divided by 2 1/12 =9/5
9/5 can also be written as 1 4/5
