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.

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
They will sum to the denominator.

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
