Answer:
Explanation:
When adding fractions it's important to make sure that the 2 or more fractions you have have the same denominator (the bottom number)
for example
1/2+2/6
is not possible at the momment because the denominator for both fractions is not the same.
We can make it the same by finding the LCM(lowest comment multiple) of the 2 numbers.
In this case the LCM is 6
So we must remebr whatever we do the bottom we do to the top.
If we times the bottom number by 3 to get 6 we have to times the top number by 3.
This makes
3/6+2/6=5/6
Adding decimals is very easy.
First thing you need to do is learn to know how many decimal places there are.
9.879
here there are 3 decimal places. You count from the last number to the decimal place
if you are doing 9.879+5.3 this has a total of 4 decimal places.
So you are going to remove the decimal places from the numbers
and add 9879+53 and then when you get your answer go to the last digit of the answer and count 4 decimal places and put in your decimal point. And there you have your answer
Hope that helps :)
