Paula writes the ratio X over three equals Y over four to help her increase the size of a two dimension shape. If the new value of X is 15 units what will be the value of y
To find the value of Y, we can set up a proportion using the ratio provided by Paula:
X / 3 = Y / 4
Given that the new value of X is 15 units, we can substitute this value into the proportion:
15 / 3 = Y / 4
Simplifying the proportion, we get:
5 = Y / 4
To find the value of Y, we can cross multiply:
5 * 4 = Y
20 = Y
Therefore, the value of Y will be 20 units.
