Question

A carpenter is building a staircase from the first floor to the second floor of a house. The distance between floors is 3.3m. Each step rises 22cm. Not counting either floor itself, how many steps will there be?

Answer 1

In order to calculate the number of steps, we need to know how much 22cm goes into 3.3m.

Formula:
1 meter = 100 centimeters
3 meters = 300 centimeters
.3 meters = 30 centimeters
3.3 meters = 330 centimeters


`(330)/(22)` =
`(165)/(11)`

And now we know, 165 divided by 11 is equal to 15.

So there you go. 15 steps.
