The Freeman family is barbecuing veggie burgers, corn cobs, and mushroom caps in their local park. If 3/8 of the items barbecued or veggie burgers, and 1/3 of the items barbecued or corn cobs, what fraction of barbecued items are mushroom caps?

7/24

Step-by-step explanation:

Let

total items barbequed = 1

Veggie burgers = 3/8

Corn cobs =1/3

Mushroom caps = x

Veggie burgers + corn cobs + x = 1

3/8 + 1/3 + x = 1

9+8 /24 + x = 1

17/24 + x = 1

x= 1 - 17/24

=24-17 /24

= 7/24

x = 7/24

Fraction of barbequed items that are mushroom's is 7/24
