Answer:
12 1/30
Explanation:
What does sum mean?
Sum is the term used for the total amount of something when two or more numbers are added.
In order to add the two fractions, they must have the same denominator.
To do this, we need to find a common denominator.
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
Multiples of 10: 10, 20, 30
Both 3 and 10 have 30 in common, so this is the common denominator.
In order to get to 30, 3 must be multiplied by 10. Whatever you do to the bottom must be done to the top and vice versa.
7 1/3 becomes 7 10/30.
4 7/10 becomes 4 21/30
Now, we add the whole numbers.
7 + 4 = 11
Now, add the fractions.
10/30 + 21/30 = 31/30
Put it all together.
11 31/30
This is an improper fraction, so we must make it a proper fraction. To do this, we divide 30 into 31. It can only go in evenly one time and has a remainder of one. The remainder is added to the whole numbers and the numerator of the fraction takes the evenly divided one.
11 + 1 1/30 This is adding the remainder to the whole number.
12 1/30 This is the result of adding the remainder and fixing the fraction.
12 1/30 is the answer.
