1) calculate percentage of yellow jelly beans from original capture
20 / (15+20+12+8) = 4/11 or 36.364%
2) apply percentage to new amount
4/11 *22 = 8 beans
The equation
a/4 = 2/3
do cross multiplication
8 = 3a
a = 8/3
Performing the expression.
= (a - 4) / 4
= (8/3 - 4) / 4
= (8-12 / 3)/4
= -4/3 / 4
= -1 / 3
So the answer is letter b.
