Question

A line segment 63cm long is to be divided into two parts in the

ratio 3:4. Find the length of each part.

​

Answer 1

let ratio will be 3x and 4x

3x + 4x = 63

7x = 63

x = 9

3x = 27 4x =36

Answer 2

Answer:

27,36

Step-by-step explanation:

let 1st part be x and 2nd part be y

according to question:

x/y=3/4, then:

x=3y/4

and the sum of the length of x and y = 63 cm

so: $\frac{3y}{4}$ + y = 63

$\frac{7y}{4}$ = 63

y= $\frac{63*4}{7}$= 36

and x= 3y/4=3*36/4= 27
