well I would make it into a proper fraction first. you can do that by taking the denominator and multiplying it by the whole number, then add the numerator

anonymous · Answer

so for 12 3/4 we would take (12 times 4) + 3 which equals 51. so the fraction =  51/4

anonymous · Answer

are they asking you to multiply the two fractions? or just change the denominators to another number?

anonymous · Answer

Subtract the two fractions
