First convert the mixed numbers into "top heavy (or "improper) fractions". Now multiply each of the improper fractions by each other - this makes the denominators the same. Now you can add both the fractions together (and cancel down if necessary).
To add fractions with the same denominators, simply add together the numerators, and cancel down if necessary. For example, 5/8 + 1/8 = 6/8. Cancelling this down to an improper fraction in its simplest form, this is equal to 3/4.
im pretty sure all u do is use a proportion
1/2 & 3/8 This is multiplication of fractions. 1/2 X 3/8 This does NOT cancel down Hence 3/16 The answer!!!!!

72/96 Cancel down by '2' 36/48 Cancel down by '3' 12/16 Cancel down by '4' 3/4 Is the fraction in its lowest terms. NB It does not have a DENOMINATOR OF '18'
46.3% = 46.3/100 But you can't have decimals in fractions so you multiply them both by 10 and you get: 463/1000 which does not cancel down.
Ratios are basically decimals, numbers, perfect squares which all come down to being fractions.As we cut fractions, same method is applied to ratios.... Cathy

No, it is quite possible for the fractions not to have common factors, even if you cross-cancel.

Factor the numerator and denominator, and then cancel any common factors.
240/300 Cancel down by #10# Hence 24/30 Cancel down by'3 8/10 Cancel down by '2' 4/5 The answer!!!!!

In order to multiply fractions with variables, factor all numerators and denominators completely. Use the rules for multiplying and dividing fractions, cancel any common factors, and leave your final answer in factored form.
