5/5 and 7/7 is equal to one
6/5 and 8/7 is greater than one
The answer is (b) greater then 1.
Step-by-step explanation: Given that Julia writes 2 fractions with the same denominator that have numerators 5 and 7. We are to find the denominator if the sum of the two fractions is less than 1.
Let 'd' be the denominator of the two fractions, then we have
Since the denominator is greater then 12, so it must be greater then 1.
Thus, the correct option is (b) greater than 1.
we need to sum two fractions that have the same denominator and the numeratos 5 and 7:
for the sum to be less than one you could have something like this:
-> where which is less than one.
for the sum to be equal to one you could have:
and for the sum to be greater than one you could have:
-> which is greater than one.
Equal to one would be 12
Greater than one the denominator could be 10
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
