Say the pair are 1/5 & 2/7 Add together and then divide by '2' 1/5 + 2/7 (7/35 + 10/35) / 2 I have do it all as one sum. The rule in maths is DO INSIDE the brackets first . (17/35)/2 = 17/35 divide 2/1 = 17/35 X 1/2 = 17/70 This is the mid-point fraction between 1/5 & 2/7 .
The two fractions are 1/6 and 3/8
That their sum is always equal to the denominator.
30/70
The sum of two fractions will only be a whole number if the fractions have a common denominator. When the denominators are different, the sum will be a fraction with a different denominator, making it impossible to be a whole number. Thus, estimating the sum of two fractions will generally result in a fraction, not a whole number.

They will sum to the denominator.
The sum of two fractions will be equal to one when the numerator and the denominator of their sum are the same. Example: 1/3 + 2/3 = 3/3 or 1

35% = 35/100 which reduces to 7/20
14 and 21 have a sum of 35 and an LCM of 42
if you are adding two fractions that are both greater than 1/2, what must be true about the sum?
1half+1half 3quarters+1quarter
