Question

The sum of one-third a number and twenty-five is as much as twice the number

Answer 1

75/7 = 105/7 (ten whole number, five over seven)

Explanation:

1/3n + 25 = 2n

n is the number

n/3 + 25/1 = 2n

n + 75/3 = 2n

cross multiply

n + 75 = 6n

75 = 7n

n = 75/7

n = ten whole number, five over seven (105/7)
