Question

Divide 120 in the ratio of 1:2:9

Answer 1

1+2+9=12
120/12=10

each unit is 10

10*1=10
10*2=20
10*9=90


120 divided into 1:2:9 is 10,20,90

Answer 2

Answer: The divided parts are 10, 20 and 90.

Step-by-step explanation: We are given to divide 120 in the ratio 1 : 2 : 9.

Let the required parts be 1x, 2x and 9x.

Then, according to the given information, we have

`1x+2x+9x=120\\\\\Rightarrow 12x=120\\\\\Rightarrow x=(120)/(12)\\\\\Rightarrow x=10.`

Therefore, we get

First part = 1 × 10 = 10,

second part = 2 × 10 = 20

and

third part = 9 × 10 = 90.

Thus, the divided parts are 10, 20 and 90.
