Answer 2

how?

Answer 3

Adelle took 84+12, or 96 pictures in all, including the unspoiled ones too. And since there are 24 pictures in each roll, you divide 96 by 24.
96/24 gives you 4.
So Adelle used 4 rolls of film.

Answer 6

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

⇒ Adelle has used a little more than 4 films

⇒ Adelle has used 5 rolls of films
