2-38. Find the missing number that makes each of the following number sentences true.

a. 15 ? = 90
c. 6. ? = 96
b. 90 = 18
?
d. = 13

Answer 1

To find the missing number in each number sentence, we solve the equations by performing the necessary calculations.

Step-by-step explanation:

In order to find the missing number that makes the number sentence true, we need to solve the equation. Let's solve each part of the question:

a. 15 ? = 90

To find the missing number, we need to divide 90 by 15. The missing number is 6.

c. 6. ? = 96

To find the missing number, we need to divide 96 by 6. The missing number is 16.

b. 90 = 18?

Here, we need to divide 90 by 18 to find out if it's equal to the missing number. 90 divided by 18 equals 5. Therefore, the missing number is 5.

d. ? = 13

In this case, the missing number is already given as 13.
