$5/7 + 3/4 = 41/28$

To add fractions, give them a denominator in common

The Lowest Common Denominator for $7$ and $4$ is $28$

That means that you should change $5/7$ into $20/28$

$(5*4)/(7*4) = 20/28$

Next, change $3/4$ into $21/28$

$(3*7)/(4*7) = 21/28$

Now you can add the like fractions

$20/28 + 21/28$

To add like fractions, add the numerators and keep the common denominator

$20/28 + 21/28 = 41/28$ $larr$ answer

You can convert the improper fraction into a mixed number if you want, but usually it is just left as an improper fraction.

$41/28 = 1(13)/(28)$ $larr$ same answer
