Question

A rope of a length 3m 60cm is cut into two piece such that the ratio of the length of the pieces is 7:5. Find the length of the larger piece​

Answer 1

Answer:

2m 10 cm

Step-by-step explanation:

Let the length of two pieces be 7x and 5x

Total length of the rope =360cm

7x+5x=360

12x=360

x=30

Length of the larger piece=210cm=2m10cm

Answer 2

Given

A rope of a length 3m 60cm is cut into two piece such that the ratio of the length of the pieces is 7:5. Find the length of the larger piece

Step-by-step explanation:

Sum of the given ratio = 7+5=12

3 m 60 cm = 360 cm

Length of the larger piece =

$7 \times 360\\ 12$

$= 7 \times 30$

$= 210 \: cm$

$210 \: cm \: = 2.1 \: m$

Hence, the length of the larger piece is 2.1 m.
