Ok so grapes,
We have 4 servings and 9.88 grams total, so to find one serving we just need to divide by 4.
9.88/4 = 2.47 per serving
Fraction left after spending = 1 - 1/3 = 2/3
Fraction saved = 3/8 x 2/3 = 1/4
Fraction left after saving = 2/3 - 1/4 = 5/12
Fraction shared with 3 people = 5/12 ÷ 3 = 5/12 x 1/3 = 5/36
Answer: 5/36
Metathod 1
4/5=27/x
mutiply 4/5 by 27/27 and multily 27/x by 4/4
108/135=108/4x
therefor
108:135=108:4x
therefor
135=4x
divide by 4
33.75=x
metahod 2
4/5=27/x
multiply oht sides by x
4/5x=27
multiply both sides by 5/4 to clear fraction
x=135/4
x=33.75
