Question

Use the five-step strategy for solving word problems to find the number or numbers described in the following exercise:

When four times the number is added to 7 times the number, the result is 44. What is the number?

Answer 1

Let the unknown number be 'x'.

Since, four times the number is added to 7 times the number, the result is 44.

Four times the number = 4x

Seven times the number = 7x

The sum of these numbers is 44.

So, 4x + 7x = 44

11x = 44

`x = (44)/(11)`

x = 4

Hence, the number is 4.
