Which of the following results in a sum or a product that is rational choose all that apply 3.12 x 1.4 √9 x √25 √2 x √3 4 + 5 n x 3molli purchased 9 apples for $3.96 molli divided $3.97 by 9 why my molli perform this calculationin order to find out how much she paid per applein order to find the total number of apples purchasedin order to calculate the total amount that she owesin order to calculate how much money she has left 

Question 1: We have to identify which of given expressions are rational expressions.

1.  

= 4.368

=

This is expressed in the form of where p and q are integers, where q is not equal to zero.

Hence, it is rational.

2.

=

= 15

= which is also expressed in the form of where p and q are integers, where q is not equal to zero.

Hence, it is rational.

3.

=

which can not be expressed in the form of where p and q are integers and q is not equal to zero.

Hence, it is not rational.

4. 4+5

= 9

= which is also expressed in the form of where p and q are integers, where q is not equal to zero.

Hence, it is rational.

5.

This expression can be rational and can not be rational. It depends on the value of 'n'.

Question 2:

Molli purchased 9 apples for $3.96.

Then, Molli divided $3.96 by 9.

Since, the cost of 9 apples = $3.96

If we have to find the cost of 1 apple, then we will divide the cost of 9 apples by the number of apples purchased.

Therefore, Cost of 1 apple = $3.96

= 0.44

Therefore, Molli divided $3.96 by 9 in order to find out how much she paid per apple.

Therefore, Option 1 is the correct answer.

24: 56

step-by-step explanation:

24 can be divided into 3 and 56 can be divided into 7, where as all the other ratios can't.

this answer is !
