Question

Visitors to the library restroom used up 3/4 of a bottle of soap in 1/2 of a day. At that rate, howmuch soap would they use up in 1 full day?

Answer 1

The information we have is:

Soap used in 1/2 day is 3/4 of a bottle.

We need to find how much soup would be used in a full day.

Since a full day is double of 1/2 day, we need to multiply the given information by 2.

Multiplying the amount of soap by 2:

`2*(3)/(4)`

When we multiply a number by a fraction, we multiply that number by the numerator:

`(2*3)/(4)`

Solving these operations:

`(6)/(4)`

Converting this to a mixed fraction:

`1(2)/(4)`

Which is the same as:

`1(1)/(2)`

Answer:

1 1/2
