Answer:
The answer is 8/7
Step-by-step explanation:
1/5 + 4/5 + 1/7
The lcm is 35
= 7/35 + 28/35 + 5/35
= (7 + 28 + 5) / 35
= 40 / 35
= 8/7
one and one sevenths
One fifth and four fifths have the same base so you can add those numerators, which equal five. The five over five can be simplified to one and then add the one over seven
