Question

From his office, a person wants to reach his house on foot which is at a distance of `5 3/4` km. If he had walked `2 1/2` km, how much distance still he has to walk to reach his house?

Answer 1

Distance of the house from office = `5 3/4` km

Distance he walked = `2 1/2` km

∴ Remaining distance = `5 3/4 - 2 1/2` km

= `5 + 3/4 - (2 + 1/2)`

= `(5 - 2) + (3/4 - 1/2)` km

= `3 + (3/4 - 2/4)` km

= `3 + ((3 - 2)/4)` km

= `3 + 1/4`

= `3 1/4` km

Distance still he has to be walked = `3 1/4` km
