a) Determine what fraction of the ingredients is butter. Simplify if possible.

b) Express this fraction as a decimal.

c) What percentage of the ingredients are salt and flour?

Answer 1

Explanation:

a.

add up all the grams to get the total

60 + 40 + 100 = 200

butter is 60 out of 200 or

60/200 or (divide top & bottom by 20)

3/10 = answer

b.

3 ÷ 10 =

.33 = answer

c.

salt =

40 ÷ 200 = 1/5 = .20 =

20% = answer

flour

100 ÷ 200 = 1/2 = .50 =

50% = answer
