Question

I HAVE 5 MINS Select the expression that makes the equation true.

5.5 x (4 ÷ 2) + 3.8 = ___

3.2 x (8 ÷ 4) + 10
4.6 + (6 ÷ 2) x 2
6.4 + (10 − 3) + 4
7.8 x (12 ÷ 6) − 0.8

Answer 1

5.5 x (4 ÷ 2) + 3.8 = 5.5 x 2 + 3.8 = 11 + 3.8 = 14.8

Now, let's check each option to see which one gives the same value:

A) 3.2 x (8 ÷ 4) + 10 = 3.2 x 2 + 10 = 6.4 + 10 = 16.4 (not equal to 14.8)

B) 4.6 + (6 ÷ 2) x 2 = 4.6 + 6 = 10.6 (not equal to 14.8)

C) 6.4 + (10 − 3) + 4 = 6.4 + 7 + 4 = 17.4 (not equal to 14.8)

D) 7.8 x (12 ÷ 6) − 0.8 = 7.8 x 2 - 0.8 = 15.6 - 0.8 = 14.8

Therefore, the expression that makes the equation true is:

7.8 x (12 ÷ 6) − 0.8
