Question

Michael has to walk 3/8 of a kilometer tyo the store. He walks 4/5 of the way.How far did he walk?

Answer 1

Given that the distance Michael has to walk to the store is 3/8 of a kilometer and he walked 4/5 of the way, then the distance he walked will be given as follows.
Distance to be covered by Michael is:
3/8×1=3/8 km
distance Michael walked was:
4/5 of 3/8
=4/5×3/8=3/10 km

Answer 2

The first thing you should do for this case is find the amount that Michael has traveled.
 For this we have to multiply the distance to the store and the percentage traveled.
 We have then:
 (3/8) * (4/5) = 12/40
 Simplifying we have:
 (12/40) * ((1/2) / (1/2)) = (6/20) * ((1/2) / (1/2)) = 3/10
 answer
 Michael has walked 3 / 10Km (80% of the way to the store)
