3 1/2 + 3 2/7 how do i solve
Put the values into improper fractions (whole number times denominator plus numerator)
7%2F2 + 23%2F7
In order to add fractions they have to have common denominators, 14 would work
divide the denominator into the common denominator, multiply numerator by that
49%2F14 + 46%2F14 = 95%2F14
to put this back into a mixed number, divide 95 by 14, the remainder is the fraction part
6 11%2F14
