Question

Khilona said that we have gone about 120km or 2/3 of the way to the camp site. So, how much farther do we have to go?

Answer 1

2/3 ÷120
3/2×120
3×60= 180
180-120=60 km further they have to go

Answer 2

Let the total distance be x. Then,
2/3 of x = 120
2/3 * x = 120 (Transpose 2/3 to R.H.S)
x = 120 ÷ 2/3
x = 120 * 3/2 ( 120 will be canceled by 2; 60 times)
x = 60 * 3
x = 180

180-120 = 60
So Khilona have to go 60km farther.
