Question

Julia writes 2 fractions with the same denominator that have numerators 5 and 7. What could the denominator be if the sum is less than 1? Equal to 1? Greater than 1?
Please explain step by step what the answers are and how.

Answer 1

Less than 1: 5/x || x = 6 or more
Equal to 1: 5/5 || a fraction is the same as a division problem, and 5 ÷ 5 = 1
Greater than 1: 5/y || y = 5 or less

Hope this helps :)
