Question

If 20 is added in 1:2 what is the result

Answer 1

Answer:

Step-by-step explanation:

Let's say the number is called x.

So 1/3 x + 20 = 2x because 2x is the double of x.

Subtract 1/3 x from both sides: 20 = 2x - 1/3 x = 5/3 x

Multiply both sides 3, so we get 3*20 = 5x = 60, so x = 12
