Question

Anna is 4ft 9in tall. Express Anna's height in feet only by using a mixed number. If necessary, simplifyvthe fraction part of the mixed number

Answer 1

So we know that there are 12 inches in a foot. With this information we can do this:$4 \frac{9}{12}$ But if you look you can see that the fraction is not simplified. How can we simplify it? Well, what is the Greatest Common Factor of 9 and 12? Well, the answer is 3! So divide 9 and 12 by three! SO the answer would be: $4 \frac{3}{4}$ I hope this helps!
