No. 1 explanation
Solution by Formulas
Apply the fractions formula for addition, to
11+37
and solve
(1×7)+(3×1)1×7
=7+37
=107
Convert to a mixed number using
long division for 10 ÷ 7 = 1R3, so
107=137
Therefore:
1/1 + 3/7 =1 3/7No. 2 explanationSolution by Formulas
Apply the fractions formula for addition, to
58+67
and solve
(5×7)+(6×8)8×7
=35+4856
=8356
Convert to a mixed number using
long division for 83 ÷ 56 = 1R27, so
8356=12756
Therefore:
5/8 + 6/7 = 1 27/56

Solution by Formulas
Apply the fractions formula for addition, to
4/5+7/9
and solve
(4×9)+(7×5)5×9
=36+3545
=7145
Convert to a mixed number using
long division for 71 ÷ 45 = 1R26, so
7145=12645
Therefore:
4/5 + 7/9 = 1 26/45
