Question

From a ribbon of 20 metres long, Sneha cut off 3 pieces of 2⅙

metre each and Janvi

cut off 2 pieces of 2⅛

each.What is the length of the ribbon left?​

Answer 1

Answer:

9 1/4

Step-by-step explanation:

20 - 3(2) - 3(1/6) - 2(2) - 2(1/8)

= 20 - 6 - 4 - 1/2 - 1/4

= 10 -1/2 - 1/4

= 9 1/4

Answer 2

Answer:

Sneha ,

2 1/6= 13/6

for 3 pieces= 3×13/6= 13/2

Janvi,

2 1/8 = 17/8

for 2 pieces= 2× 17/8= 17/4

Sum of all the pieces of ribbon cut by Sneha amd Janvi = 13/2+ 17/4 = 43/4

Remaining length of the ribbon = 20-43/4= 37/4

37/4= 9 1/4 metres.
