Question

There are 15 floors of an office building each floor is 10 2/5 feet tall 24 9/10 feet of the building are completed 1 1/4 feet of the building can be finished each day how many days are needed to complete the building

Answer 1

104.88 (rounded 105)

Explanation:

The total height of the building is 156'. I got that by multiplying 10.4 by 15.

Then I made an equation.

156 = 1.25x + 24.9

-24.9 -24.9

131.1 = 1.25x

/1.25 /1.25

104.88 = x

x represents the number of days.

So it will take 104.88 days or if your teacher wants you to round, it will take 105 days to finish the building.

Answer 2

If there are 15 floor and each one is 10 2/5 tall then multiply that together to get 156. Then subtract 24 9/10 from that because that has already been completed to get 131 1/10. Then divide 1 1/4 by 131 1/10 to get 104 22/25.
