Terry writes the ratio X slash 9 = Y slash 18 to help her reduce the size of two dimensional shapes if the the new value of Y is five units what will be the value of X?
To find the value of X, we first need to substitute the given value of Y into the ratio equation.
X/9 = 5/18
Next, we can cross multiply to solve for X.
18X = 5 * 9
18X = 45
Finally, divide both sides of the equation by 18 to solve for X.
X = 45/18
Simplifying the fraction, we get:
X = 2.5
Therefore, the value of X is 2.5 units.
