Question

From the chain 11m long two pieces of length 18/5and23/10are cut off. What is the length of remaining chain​

Answer 1

Answer:;41/10

Step-by-step explanation:

Length of the chain = 11m

First piece of length that is cut off = 18/5

Second piece of length that is cut off = 23/10 .

So , Total piece of length that is cut off

= 18/5 + 23/10

= L.C.M of 5 and 10 is 10

= (18×2/5×2) + (23×1/10×1)

= 36/10 + 23/10

= 59/10.cm.

Total piece of length that is cut of = 59/10cm .

Length of remaining chain = total

length of the chain - pice of length

that is cut off .

= 11 cm - 59/10 cm

= 41/10 cm.

So Lenth of the remain chain is 41/10 cm
