Question

The sum of one - fifth of a number and 3 whole 7/10 is 7. Find the number.

Answer 1

Answer:

173/6

Step-by-step explanation:

Let the number be x.

1/5x + 3 7/10 = 7

Writing this as an improper fraction,

1/5x = 7–37/30

1/5x = 210/30 - 37/30

1/5x = 173/30

So, x = (173/30) x 5 = 173/6.
