In order to add these, the denominator has to be the same. Here, the least common denominator is 30.
Multiply the denominator of 4/3 by 10 to get 30. Whatever you do to the bottom you must do to the top or it will be a different number. So 4 must also be multiplied by 10 to become 40. Thus 4/3 becomes 40/30.
Now we must make the denominator of 7/10 the same as the first. So multiply the denominator by 3, and do the same to the numerator. So 7/10 becomes 21/30.
Now we can add the two equations:
4/3 + 7/10
= 40/30 + 21/30
= 61/30
Find the common denominator. The common denominator is 30. That is easily found by multiplying the two denominators.
Whatever you do to one part of a fraction must be done to the other part. For example if you multiply the denominator by 10 then the numerator must also be multiplied by 10.
4/3 + 7/10 equals 40/30 + 21/30 equals 61/30
61/30 can be simplified by factoring out a two on the top (numerator) and bottom (denominator)
First convert it into 60/30+ 1/30 which equals 2 1/30 as your final answer
