1. From a ribbon which is 22 m long, two pieces of
1/२

lengths 5-m and 3. m are cut off. What is the
5/१०

length of the remaining ribbon?​

Answer 1

Answer:

28/5 cm

Step-by-step explanation:

Let the length of the remaining ribbon = X cm

Total length of Ribbon = 22 cm

Sum of length of two pieces of ribbon = 51/5 + 31/5 = 51+31/5 = 82/5 cm.

Therefore,

Sum of two pieces of the length of ribbon + Length of remaining ribbon = 22

X + 82/5 = 22

5X + 82/5 = 22

5X + 82 = 22 × 5

5X + 82 = 110

5X = 110 - 82

5X = 28

X = 28/5 cm

Hence,

Length of remaining ribbon = X = 28/5 cm
