Q.8. From a tape 5 1 4 metres long, Sourabh cut off 2 7 of it; what length of tape is cut?

lenght of tape = 5 1/4 m
                     = 21/4
cut off tape = 2/7
therefore lenght of cut off tape will be =  21/4 - 2/7 
LCM of 4&7 = 28
21/4 x 7/7 = 147/28
& 2/7 x 4/4 = 8/ 28
therefore 147/28 - 8/28 = 139/28 = 4 27/28 m

lenght of tape = 5 1/4 m
? ? ? ? ? ? ? ? ? ?. ?= 21/4
Length of cutted tape = 2/7
lenght of cut off tape will be = ?21/4 - 2/7?
LCM of 4 and 7 = 28
21/4 x 7/7 = 147/28
And 2/7 x 4/4 = 8/ 28
therefore 147/28 - 8/28 = 139/28
= 4 27/28 m
