We have already learn t definition of fraction, different types of fractions in a very easy method in my previous post. Lets learn more about it such as how to solve fractions. Below i have a few problems mentioned which will show you easy method of addition of fractions.
Addition of fraction:-
a) 5/8+2/8
Here we see the denominator is the same therefore we need to add only the numerator.
5/8+2/8=5+2/8
=7/8 (answer)
b) Add 3/9 and 4/9
= 3/9+4/9= 3+4/9(as mentioned earlier if the denominators are the same they need to be written the same)
=7/9 (answer)
Now what do you think should be done if the denominators are not the same or they are different. Lets look into that as well.
c) 2/5+5/8
Here we see the denominator are different therefore firstly we will have to find the LCM of the denominator.
LCM of 5 and 8 is 40.
=2/5+5/8= 2(8)+5(5)/40
=16+25/40
=41/40
therefore the answer is 41/40
Did you find this post interesting? Did you learn how to add fractions with two different methods, There are online fraction calculators also, work on your problems and check your answers using these calculators. Lets learn more on fractions in my next post.
