3/20 of the budget

To find the part of the budget that is left for decorations and snacks, you need to subtract the portions used for the DJ and chaperones from the whole budget.

The portion used for the DJ is 3/5 of the budget.
The portion used for the chaperones is 1/4 of the budget.

To find the remaining portion, you subtract the sum of the DJ and chaperones portions from the whole budget:

1 - (3/5 + 1/4)

Find a common denominator for 5 and 4, which is 20:

1 - (12/20 + 5/20)
1 - (17/20)

This means that 17/20 of the budget is used for the DJ and chaperones, leaving 3/20 of the budget for decorations and snacks.
