Q.8. From a tape metres long, Sourabh cut off 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
= 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
