Question

Please help me quick!!

Use parentheses to rewrite the numerical expression to have the given value.

15+17/8-4

Answer 1

13.125

Explanation:

Answer 2

(15+17)/(8-4)

Explanation:

Normally you would calculate the 17/8 first giving:

15+17/8-4 = 13.125

You can add parentheses like this giving:

(15+17)/8-4 = 0

This doesn’t work then:

15+17/(8-4)=19.25

Then we can try:

(15+17)/(8-4)=32/4=…8 !!!

So that‘s the answer! :)
