Question

a builder has built 1/6 of the floors of a new skyscraper. If the builder has built 13 floors, how many floors will the skyscraper have when it is finished? Write and solve an equation to find the answer.

Answer 1

13*6=78

Explanation:

If one part of something is equal to 13, then 6 parts are equal to 13*6. Let us denote that "something" by x, and we get

`x = 6 * (1)/(6) x = 6 * 13`

Which is obviously an identity

Answer 2

Answer: 78 floors total

Explanation:

if 13=1/6

6 x 13=78
