Question

a rope is 8.4 metre is cut into 0.4 metre long pieces. how many pieaces can we make​

Answer 1

Answer:

• We can make 21 pieces of rope.

Step-by-step explanation:

Given that:

• Length of a rope is 8.4 metres.
• It is cut into 0.4 metre long pieces.

To Find:

• How many pieces can be make.

Process:

Here we have been provided with the length of a rope (8.4 m) and we have been given that the rope is to be cut in 0.4 m long pieces. So, to find the number of pieces we can make we have to divide the length of the rope (8.4 m) by the length of each piece(0.4 m). So let's solve.

Solution:

Length of the rope = 8.4 m

Length of one piece of rope = 0.4 m

No. of pieces we can make =  $\sf\dfrac{Length \:of \:rope}{Length\:of\:a\:piece}$

$= \sf\dfrac{8.4}{0.4}$

Multiplying both numerator and denominator by 10,

$= \sf\dfrac{84\times10}{4\times10}$

$= \sf\dfrac{84}{4}$

Dividing 84 by 4,

$= \sf{21}$

Hence, 21 pieces of rope measuring 0.4 m can be made out of a rope of 8.4 m.
