Answer:
option c: is the answer of your question
You cannot add two fractions with different denominators (the bottom number) so you have to convert them so that they do.
The lowest common denominator (LCD) for 4 and 5 is 20. 4 is multiplied into 20 5 times, so multiply 5/5 by the whole fraction so that you have:
1/4x5/5=5/20
And as for 5, it goes into 20 4 times, so you multiply 4/4 by the whole fraction so that you have:
3/5x4/4=12/20
NOW, you can add both fractions together. Because this is addition, you do NOT add the denominators, only add the numerators.
5/20+12/20=17/20
The fraction 17/20 cannot be simplified any further, so that is your answer. Hope this helps :-)
