Question

Mr. Ali cut a wooden plank into three parts in the ratio 2:3:8. The longest part was 72 centimeters

Answer 1

117 centimeters

Explanation:

Since the longest pieces is 72 centimeters and it’s ratio is 8, that means the individual unit of the ratio is 9 (72/8=9). You can multiply each part of the ratio by 9

2x9=18

3x9=27

We already know the third part of the ratio is 72. Add all of it together to get the original length.

18+27+72=117 cm
