Answer:
24
Explanation:
30 cookies, 4/5 are oatmeal
Multiply fractions straight across the equation, numerator times numerator and denominator times denominator.
30/1 x 4/5 = 120/5
Reduce 120/5 by dividing denominator and numerator by 5
120 / 5 = 24/1 = 24 cookies were oatmeal.
OR
30/5 = 6 = 1/5 of 30
4 x 6 = 24 cookies were oatmeal
Hardly worth heating the oven and getting all the pans dirty for such a small batch
