The easiest way is to find the 'common denominator' then add the numerators:
1. Finding a common denominatorThe two denominators are 7 and 9, and we need to find the first number that is a multiple of both. Multiplying the two always gives you one (but might not be the lowest number that does), in this case 7*9=63 . 2. Convert both fractions to use the new denominatorTo convert we multiply both sides of each fraction until we get to the new denominator:The answer is 62/63.
This fraction cannot be simplified, but in other cases like this you should to get a simpler answer.
55 over 63. Use a calculator.
five seventh
5/7 ; five sevenths
That is 9 and 5 ninths.
28/63
It is: 15/9 or1 and 2/3
1 29/63
1 and 1 ninths
10/9
32/27
Nine sevenths, or one and two sevenths.
9 and 7/18
