Step-by-step explanation:

A P E X

20%

Step-by-step explanation:

Two bags contain marbles, while Bag A contains 112 marbles, bag B contains 140 marbles.

Number of marbles in bag A = 112

Number of marbles in bag B = 140

Differences in the marbles

= 140-112= 28

Percent fewer marbles in Bag A than Bag B will be:

Difference in marbles in the bags divided by the marbles in bag B multiplied by 100.

= 28/140 × 100

= 1/5 × 100

= 20%
