Question

from a rope of length40m 50cm,how many pieces of rope can be made of length 2_1/4m each ​

Answer 1

Answer:

18 pieces

Step-by-step explanation:

Length of the rope =  40m 50cm

= 40m + 50 × 1/ 100m   [∵1 cm = 1/100 m]

 

​ = 40 m + 50/100 m

= (40 + 5/10 )m

= 400 + 5/ 10 m

   = 405/10 m

Length of each piece of rope to be cut = 2_1/4 m = 9/4 m

Number of pieces = 405/10 ÷ 9/​4

= 405/10  × 4/9

=18

∴18 pieces of rope can be cut of length 2_1/4 m each.
