Find the unknown: 4:2:3 = x : 18: 27

x=36

4 : 2 : 3 = x : 18 : 27

=> 36:18:27

Step-by-step explanation:

4 : 2 : 3 = x : 18 : 27

We have to find the value of x.

In ratios, all the numbers must be divided by the same number

from the expression above we can identify that:

2*9 = 18

3*9 = 27

we see that right side of equation is achieved by multiplying each value of left side by nine

so, 4*9 = 36

i. e x=36.

36

Step-by-step explanation:

note that 3 parts of the ratio represents 27, hence

27 : 3 = 9 ← value of 1 part of the ratio

Hence

x = 9 * 4 = 36
