The Scale Factor of 40/81 is the relative difference of one fraction or number (a) to another fraction or number prime (a′). In other words, 40/81 is what you multiply (number a) by to get (number a prime).
In a multiplication problem, we have a multiplier, multiplicand, and a product. You could say that (a) is the multiplier, the Scale Factor of 40/81 is the multiplicand, and (a′) is the product:
multiplier × multiplicand = product
multiplier × scale factor = product
a × 40/81 = a′
In the calculator below, you can enter the multiplier (a) as a fraction. We will then multiply it by the Scale Factor of 40/81 and give you the product (a′) in its simplest form possible.
You may also be interested to know that a Scale Factor of 40/81 is a Reduction Scale Factor because it makes a fraction or number smaller when it is multiplied by 40/81.
