Question

A rope of length 3m 20cm is cut into 2 pieces such that the ratio of the lengths of the pieces is 7:9. Find the length of the larger piece .(in cm)​

Answer 1

Answer:

Step-by-step explanation:

Length of Rope= 3 m 20 cm= 300+20 cm= 320 cm

Given that the rope is cut into 2 parts, having the ratio of 7:9 by length.

Let the length of pieces be 7x, 9x.

Therefore,

7x+9x= 320 cm

16x = 320

x= 20

Therefore, Larger piece (9x) has the length of

9x= 9(20)= 180 cm.
