Answer 1

She has 84 pictures and 12 others were bad for a total of 84+12 = 96 pictures were taken.

Divide the total pictures taken by 24 per roll:

96 / 24 = 4

She used 4 rolls of film.

Answer 2

Find the total pictures taken:

Total pictures that turns out good = 84

Total pictures that turns out spoilt = 12

Total pictures taken = 84 + 12 = 100

Find the number of rolls used:

1 roll = 24 pictures

Number of rolls = 100 ÷ 24 = 4.17
