Add: 1⁄5 + 4⁄5 + 1⁄7

one and one sevenths

Step-by-step explanation:

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

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
