Let x be the remaining distance. We want to work out what x is.Uma wrote:Hi

We are told that two thirds of the remaining distance is 16 km.
So two thirds of x = 16 km
so 2/3 * x = 16 km
so 2 * x = 16 km *3 (multiply both sides by 3)
so 2* x = 48 km
so x = 48 km / 2 (divide both sides by 2)
so x = 24 km

I get the children who struggle with these to draw a rectangle, which represents the whole. In this case the rectangle would be cut into three pieces. We know that two out of three total 16. So each piece has 8 inside. 16 + 8 = 24.
