The Freeman family is barbecuing veggie burgers, corn cobs, and mushroom caps in their local park. If 3/8 of the items barbecued
KatRina [158]

Answer:

7/24

Step-by-step explanation:

Everything they are grilling is an amount of 1.

Then each item is a fraction of 1.

Add 3/8 and 1/3 and subtract from 1.

3/8 + 1/3 = 9/24 + 8/24 = 17/24

The veggie burgers and corn account for 17/24 of the total.

To find the fraction of mushroom, we subtract 17/24 from 1.

1 - 17/24 = 24/24 - 17/24 = 7/24

Answer: 7/24
