Adding and subtracting fractions 3/5 + 4/7

Answer:

1 and 6/35

Step-by-step explanation:

You would want to multiply the denominators with the same number.

5×7

Multiply the numerators as well.

3×7 and 4×5

The fractions you would have now is 21/35 and 20/35, you can now add them up without having difficulties if the denominator is the same number.

You can also change it into decimals but I suggest this strategy.
