Solve the proportion for X.<br> 5/2.5= <br> X/2<br> 1<br> 4<br> 5.5<br> 6.25
Sav [38]

Answer:

\large \boxed{X = 4}

Step-by-step explanation:

5/2.5 = X/2

To solve a proportion, use the following equation:

(numerator * opposite denominator) =  (numerator * opposite denominator)

Substitute in given numbers

(5 * 2) = (X * 2.5)

Multiply to simplify

10 = 2.5X

Divide both sides of this equation by 2.5

\large \boxed{X = 4}

Hope this helps :)
