Question

Skill2.1.F-7A printer has 18 rolls of newsprint in the warehouse. What fraction of this total will remain if six rolls are used?of the total rolls will remain after six rolls have been used.(Type a simplified fraction.)

Answer 1

When 6 rolls are used, there are 18 - 6 = 12 remaninig rolls. 12 is the total of rolls remaining, then, we need to find the fraction of 18 that corresponds to 12, being 18 the total. For that, we just need to divide them:

`(12)/(18)`

We can now simplify. We can divide both numerator and denominator by 6, since 6*2 = 12 and 6*3 = 18:

`(12)/(18)=(2)/(3)`

Then, 12 is two thirds of 18. We can say that after 6 of the 18 rolls are used, the remaining amount of rolls is two thirds of the previous amount of rolls.
