Question

A pole is cut into two pieces in the ratio 6:7.If the total length is 117cm,find the length of each part.

Answer 1

let constant be x
6x+7x=117
13x=117
x=117÷13
x=9
6x=6×9=54
7x=7×9=63
54&63 is the length of each part
please give me brainliest ☺

Answer 2

Given: Total length of piece= 117cm

Ratio of 1 part= 6
Ratio of 2 part= 7

Ratio of first part to second part= 6:7

Sum of ratio= 6+7= 13

Length of 1 part=( 6/13)× 117
= 6×9= 54cm

Length of 2part = (7 /13)/117
= 7×9= 63cm
Hence length of each part each 54 cm & 63 cm.....
