Question

When 70% of a number is added to the number, the result is 238

Answer 1

x= the number

x+ (x*70)/100 = 238

x+70x/100 = 238

x+7x/10 = 238

(10x+7x)/10 = 2380/10

17x=2380

x=140

number 140

we check

140+(140*70)/100=140+98=238

Answer 2

The number is 140.

Explanation:

X = the number in question

X + (70% times X) = 238

X + (0.70X) = 238
1.70X = 238

X = 238/1.70

X = 140
