A pupil

A pupil in our street goes to school by taking a bus to travel 1 1/2 km and then walks 1 1/4 km. What is the distance between his school and house?

Correct answer:

x =  2 34 = 11/4 km

Step-by-step explanation:

a=121=1+21=21 2+1=22+1=23=1.5 km b=141=1+41=41 4+1=44+1=45=1.25 km  x=a+b=23+45=46+45=46+5=411=411 km=243 km=2.75 km
