Question

Monika had a 12.40 m long ribbon. She cut 16 smaller pieces each of length 0.48 m from it. How many ribbon in cm is left with her
​

Answer 1

Answer:

For this question, we try to find a number that divides 16 and 20 perfectly without leaving any remainder behind.

Such numbers are 1,2 and 4.

If 1 is considered,then 16 pieces and 20 pieces of equal length (1m) will be obtained from 16m and 20m rope respectively

If 2 is considered, then 8 pieces and 10 pieces of equal length(2m) will be obtained from 16m and 20m rope respectively

If 4 is considered, then 4 pieces and 5 pieces of equal length (4m) will be obtained from 16m and 20m rope respectively.
