Answer 3

To solve the proportion X:2 = 13/36 : 27/85 : 1/4, you can use cross-multiplication.

First, find the ratios on the right side of the proportion:

1. 13/36 : 27/85 : 1/4

Now, set up the proportion with X:

X/2 = (13/36) / (27/85)

Now, cross-multiply:

X/2 = (13/36) * (85/27)

To simplify this, first find the products of the numerators and denominators:

X/2 = (13 * 85) / (36 * 27)

Now, calculate those products:

X/2 = 1105 / 972

To isolate X, multiply both sides of the equation by 2:

X = (1105 / 972) * 2

Now, calculate this:

X ≈ 2.27 (rounded to two decimal places)

So, X is approximately equal to 2.27.
