3. a) p∝1/m
P=k/m
48=k/9
48×9=k
k=432
the equation is: p=432/m
b) p∝1/m
P=k/m
P=432/12
P=36
<span>A fraction is normally expressed in its lowest form. It means that there is no common factor for the numerator and denominator. A common factor is a number that can divide both the numerator and the denominator without a remainder.
A fraction in its lowest form can have any number of equivalent fractions. To create equivalent fractions, multiply both the denominator and the denominator by the same number.
