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:
[tex]2\times\frac{3}{4}[/tex]When we multiply a number by a fraction, we multiply that number by the numerator:
[tex]\frac{2\times3}{4}[/tex]Solving these operations:
[tex]\frac{6}{4}[/tex]Converting this to a mixed fraction:
[tex]1\frac{2}{4}[/tex]Which is the same as:
[tex]1\frac{1}{2}[/tex]Answer:
1 1/2
