Question

From a 72 metre long rope, pieces of equal sizes are cut. If the length of one piece is 2 whole 2/5 m, find the no of such pieces.​

Answer 1

$\bf{\underline{\underline \blue{Solution:-}}}$

$\sf\underline{\red{\:\:\: AnswEr:-\:\:\:}}$

• The number of such pieces = 30

$\sf\underline{\red{\:\:\: Given:-\:\:\:}}$

• From a 72 metre long rope, pieces of equal sizes are cut. If the length of one piece is 2 whole 2/5 m.

$\sf\underline{\red{\:\:\: Need\:To\: Find:-\:\:\:}}$

• The number of such pieces = ?

$\bf{\underline{\underline \blue{Explanation:-}}}$

$\sf\underline{\red{\:\:\: We\:Know\: That:-\:\:\:}}$

$\bigstar \: \boxed{ \sf \: One\:piece \: length \times Number = Total \: Length}$

$\sf\underline{\green{\:\:\: Now,Putting\:the\: values:-\:\:\:}}$

$\dashrightarrow \sf {2 \frac{2}{5} \times Number = 72}$

$\dashrightarrow \sf {\frac{12}{5} \times Number = 72}$

$\dashrightarrow \sf {72 \times \frac{5}{12} = Number }$

$\dashrightarrow \sf { 6 \times 5 = Number}$

$\dashrightarrow \sf {Number = 30}$

$\sf\underline{\green{\:\:\: ThereFore:-\:\:\:}}$

• The number of such pieces = 30

$\rule{200}{2}$

Answer 2

Answer:

length of a rope=72m

length of one pieces=2/5m

therefore no.of pieces=72/2/5

=72x5/2

=7x5

=35
