Answer 1

we know that

1 1/4 cups of sugar to make 20 cookies

so

Applying proportion

Find out how many cups of sugar to make 6 cookies

but first

convert mixed numbers to an improper fraction

1 1/4=1+1/4=5/4 cup of sugar

(5/4)/20=x/6

solve for x

x=[(5/4)/20]*6

x=(5/80)*6

x=30/80

x=3/8

the answer is 3/8 cups of sugar
