Question

Scott is saving coins in a jar. Last week, the jar was 1/4 full. This week, he added more coins, and the jar is now 1/2 full. How much of the jar did Scott fill this week?

Answer 1

He filled his jar 1/4 more this week.

Explanation:

The explanation is very simple, you know that he added 1/4 coins last week and this week he added more coins that filled the jar half way:

1/2 - 1/4 = 1/4

or you can also use:

1/4 + 1/4 = 1/2

Answer 2

Scott filled (1/2 - 1/4) of the jar, or 1/4 of the jar this week.
