The fraction of the budget needed for the DJ is 3/5 and the fraction of the budget needed for the chaperones is 1/4. The fraction of the budget left for decorations and snacks can be found by subtracting these fractions from 1.
1 - 3/5 - 1/4
To find a common denominator, we multiply the first fraction by 4/4 and the second fraction by 5/5:
1 - (3/5)(4/4) - (1/4)(5/5)
= 1 - 12/20 - 5/20
Now we can subtract the fractions:
1 - 12/20 - 5/20
= (20/20) - (17/20)
= 3/20
Therefore, there is 3/20 of the budget left to pay for decorations and snacks.
