Question

3/5 of a road is to be resurfaced if the road is 2 3/5 km long what length in kilometres is to be resurfaced. Please answer with method

Answer 1

Given :

Total length of road = 2 $\dfrac{3}{5}$ km

Part of road to be resurfaced = $\dfrac{3}{5}$th

To Find :

The length in kilometres is to be resurfaced.

Solution :

Let The length in kilometres is to be resurfaced = x km

∵ Total length of road = 2 $\dfrac{3}{5}$ km = 2 + $\dfrac{3}{5}$ = $\dfrac{13}{5}$ km

And

Part of road to be resurfaced = $\dfrac{3}{5}$th

i.e Part of road to be resurfaced = $\dfrac{3}{5}$th of $\dfrac{13}{5}$ km

                                                      = $\dfrac{3 \times 13}{5 \times 5}$

                                                      = $\dfrac{39}{25}$ km

Hence, The length in kilometres is to be resurfaced is $\dfrac{39}{25}$ km . Answer
