# What does a scale factor of 3 mean?

## What does a scale factor of 3 mean?

A scale factor of 3 means that the new shape is three times the size of the original.

## What is a scale of 2?

For example, a scale factor of 2 means that the new shape is double the size of the original shape. When a scale factor is a fraction the shape decreases in size, but we still call this an enlargement.

**What is the scale factor of 1 and 3?**

A scale factor of 1:3 means that one triangle is 3 times bigger than the other, for example. So, if the small triangle has a perimeter of 27, the big triangle has a perimeter 3 times as big. Doing the math, 3⋅27=81 – the big triangle’s perimeter, then, is 81 units.

**What is the meaning of scale factor?**

A scale factor is a number which multiplies (“scales”) a quantity. For example,the “C” in y = Cx is the scale factor for x. If the equation were y = 5x, then the factor would be 5.

### What is the scale factor of 3 and 7?

The Scale Factor of 3/7 is the relative difference of one fraction or number (a) to another fraction or number prime (a′). In other words, 3/7 is what you multiply (number a) by to get (number a prime).

### How do I find the scale factor?

The basic formula to find the scale factor of a figure is: Scale factor = Dimension of the new shape ÷ Dimension of the original shape.

**What does a scale factor of 3 2 mean?**

This gives us the ratios 12/8, 15/10, and 9/6. These all reduce to the fraction 3/2, or 1 1/2 (the second triangle is a little less than twice as big). We usually leave the scale factor as a fraction, so we would say that the scale factor is 3/2.

**How do you scale factor?**

The basic formula that is used for calculating the scale factor is, Scale factor = Dimension of the new shape ÷ Dimension of the original shape. In case, if the original figure is scaled up, the formula is written as, Scale factor = Larger figure dimensions ÷ Smaller figure dimensions.
