What means to divide the numerator and the denominator of the ratio by the same factor?
To divide the numerator and the denominator of a ratio by the same factor means to simplify or reduce the ratio. This is done by dividing both numbers in the ratio by their greatest common factor, which results in an equivalent ratio.
How do you do ratio of 18000 to 63000?
You divide 18000 and 63000 by their greatest common factor, which is 9000. So 18000:63000 = 2:7
Why do the fours in the numerator and denominator cancel out?
They are a common factor and any common factor in the numerator and denominator of a ratio can be cancelled out.
How can you tell when a ratio is in simplest form?
Use a formula or algorithm for finding the greatest common factor. When in their simplest form, the numbers in a ratio have a GCF of 1. this is often easy to spot without formally checking; for instance, if any of the numbers are prime, then they are in their simplest ratio.
How do you simplify the ratio 21.15?
Divide both sides of the ratio by any common factor until the only common factor is 3; this can be done in one step by dividing both sides by the highest common factor of the sides. For 21:15 the highest common factor is 3, so divide both sides by 3. Thus: It would simplify to 7:5
When the terms of a ratio are divided by their greatest common factor the resulting ratio is in?

What if a ratio does not have a common factor?
A ratio always has a common factor, even if it's only 1.
How do you reduce a ratio in lowers term?
Find a common factor of the number in the ratio. If the common factor is 1, then the ratio cannot be reduced. Otherwise, divide both numbers of the ratio by the common factor. It will have been reduced.
