4+5 / 10 • look for the LCD of 5 and 2 which is 10 then 5 goes 2 times into 10 the multiply by 2 = 4. Then 2 goes 5 times into 10 then multiply by 1 = 5.
To add two fractions they must be over a common denominator, which for this problem is 10. To put each fraction over a common denominator we must multiply each fraction by the appropriate form of 1. 2/5 + 1/2 ( 2/2 X 2/5 ) + (5/5 X 1/2 ) --> 4/10 + 5/10
We can now add the numerators of the two fractions over the common denominator: 4/10 + 5/10 ---> 4+5/10 ---> 9/10.
Hope this helps! I know what does though, marking me brainliest.
