Example: 16/48 x 2/3
The GCF of 16 and 48 is 16, so 16 can be divided into both numbers, simplifying 16/48 to 1/3. The problem then becomes 1/3 x 2/3 = 2/9

Why do you have to switch the numerator and denominator when dividing fractions?
This is because dividing by a number is the same as multiplying by its reciprocal.
Why is multiplying or dividing the numerator and the denominator by the same number the same as multiplying or dividing the fraction by 1?
Because multiplying or dividing them by the same NON-ZERO number does not alter their ratio.
What is the definition of dividing a fraction?
Dividing a friction is multiplying by its reciprocal. The reciprocal of a fraction is the numerator and the denominator switched around.
How can you write 3.2 as a fraction?
To write 3.2 as a fraction, we can convert it to its equivalent fraction form by multiplying both the numerator and denominator by 10. This gives us 32/10. Simplifying this fraction by dividing both the numerator and denominator by their greatest common divisor, we get the simplified fraction 16/5.
Why is multiplying or dividing the numerator and denominator by the same nonzero number the same as multiplying or dividing the fraction the fraction by 1?
Because doing so is equivalent to multiplying or dividing by x/x, which can be cancelled down to 1.

How do you make fraction to decimal?
by dividing the numerator by the denominator
When dividing fractions is a reciprocal used by multiplying?
Yes. One method for dividing fractions is to multiply the numerator fraction by the reciprocal of the denominator fraction.
What is simplifying a fraction to simplest form?
Find the GCF of the numerator and the denominator and divide them both by it. If the GCF is 1, the fraction is in its simplest form.
