Question

Shalini used 1 m 50 cm of red ribbon and 4 m 28 cm of blue ribbon to make a flower. How much ribbon ​did she use in all?

Answer 1

Solution:

We know that 1m = 100 cm
Length of red ribbon = 1m 50 cm=100 cm +50 cm = 150 cm
Length of blue ribbon = 4m 28 cm = 400 cm+ 28 cm= 428 cm.
Total length of ribbon used = 150 cm+ 428 cm= 578 cm.
