Question

Anoton unpacks 4 dozen glasses from a box. He finds 5/12 of the glasses are broken. How many glasses are broken?

Answer 1

Answer: 20

============================================================

Work Shown:

1 dozen glasses = 12 glasses

4 dozen glasses = 48 glasses

48*(5/12) = 20 glasses are broken

--------------

Alternative route:

5 glasses out of 12 are broken

This is the same as saying 5 glasses out of 1 dozen are broken.

Multiply both values by 4 to get 4*5 = 20 glasses broken out of 4*1 = 4 dozen.

Answer 2

Dozen; A set of 12

4 dozen:- 4 x 12 = 48 glasses in total

5/12 of the 48 glasses are wasted

5/12 x 48 = 20 glasses are broken
