Deep knowledge of dividing fractions!
Dividing fractions is very straightforward once you know how to multiply fractions
It is important to explain a thing or two before showing you how to divide fractions.
Look at this fraction 2/3
In the lesson about fractions, we called 2 the numerator and 3 the denominator.
You can also call 2 the dividend and 3 the divisor.
These terms are used when doing long division; When we divide fractions, these are also used to describe the operation.
Now,look at the fractions (2/5) /(4/3)
I put parentheses to avoid confusion, but, basically, what you have is a fraction divided by another fraction.
Whenever a fraction is divided by another, we call this a complex fraction.
Here, the dividend is 2/5 and the divisor is 4/7
When you divide fractions,invert the divisor and multiply the inverted divisor by the dividend.
The inverted divisor is called the reciprocal
Inverting a fraction means that your numerator will become your denominator and your denominator will become your numerator
example: invert 2/3
You get 3/2
Now try to do (2/5)/(4/3)
(2/5)/(4/3) = 2/5 times 3/4 = 6/20
To simplify 6/20, get the greatest common factor of 6 and 20.
GCF(6,20) = 2
Divide both numerator and denominator by 2
You get 3/10
Example: (3/8)/(3/4)= 3/8 times (4/3)=12/24=1/2
I made a calculator. Use it to practice.
