Two improper fractions have a numerator of 17. The equivalent mixed numbers are 3?/? and 1?/?. What could the mixed numbers be?
Llana [10]
The times plus method.... is where a mixed number.... for example, to get the improper fraction of 3 1/4, you multiply 4 and three, and add that number with 1. (try writing it on a piece of paper, times between the whole number and denominator, and a plus between the whole number and the numerator.) anyway we are going to use the reverse for this.

SO the numerator is 17, and 17 is divisible by 5..... 3 times (u get where I'm going??)  and there's 2 left over so...... the answer for that one should be 3 2/5
Since 3 x 5= 15+2 is 17 ;)))


Moving ON for the one....pick like 15 or 16 to be the denominator.... and subtract the 15 or 16 from 17, and the number you get is your numerator...
