Question

Neha finished one race in 3(1/2) minute 13 and Geeta in 13/4 minutes. Find out who 4 finished the race in lesser time and how much time?

Answer 1

Neha finished race = 3(1/2) minutes or 7/2 minutes 

Geeta finished race = 13/4 minutes 

L.C.M. of 2 and 4 = 4 

On making fraction 7/2 and 13/4 like fractions

(7/2) x (2/2) = (14/4)

(13/4) x (1/1) = 13/4 

Thus, 14/4 minutes or Neha took more time and geeta took less time. 

∴ Geeta took less time = (14/4) – (13/4) = (14 - 13)/4 

= 1/4 min.
