Question

3/4+6/7+4/5

Answer 1

\(=\dfrac{3\times35}{4\times35}+\dfrac{6\times20}{7\times20}+\dfrac{4\times28}{5\times28}\\ =\dfrac{105+120+112}{140}\\ =\dfrac{337}{140}\)

Answer 2

`3/4 + 6/7+ 4/5`

`= 105/140 + 120/140 + 112/140`

`= 337/140`

Answer 3

`3/4+6/7+4/5 = 105 / 140 + 120/140 + 112/140 = 337/140`
