1. Answer :
1/5 + 2/5
The given two fractions have the same denominator. That is 5.
So, take the denominator once and add the numerators.
= (1 + 2)/5
= 3/5
Therefore,
1/5 + 2/5 = 3/5
2. Answer :
5/14 + 2/14
The given two fractions have the same denominator. That is 14.
So, take the denominator once and add the numerators.
= (5 + 2)/14
= 7/14
Simplify.
= 1/2
Therefore,
5/14 + 2/14 = 1/2
3. Answer :
1/5 + 2/5 + 2/5
The given fractions have the same denominator. That is 5.
So, take the denominator once and add the numerators.
= (1 + 2 + 2)/5
= 5/5
Simplify.
= 5/5
Therefore,
1/5 + 2/5 + 2/5 = 1
4. Answer :
5/24 + 7/24 + 6/24
The given fractions have the same denominator. That is 24.
So, take the denominator once and add the numerators.
= (5 + 7 + 6)/24
= 18/24
Simplify.
= 3/4
Therefore,
5/24 + 7/24 + 6/24 = 3/4
5. Answer :
2/13 + 7/13 + 12/13 + 5/13
The given fractions have the same denominator. That is 13.
So, take the denominator once and add the numerators.
= (2 + 7 + 12 + 5)/13
= 26/13
Simplify.
= 2
Therefore,
2/13 + 7/13 + 12/13 + 5/13 = 2
6. Answer :
Amount of pizza that Linda and kemka ate together :
= 2/7 + 3/7
The fractions above have the same denominator. That is 7.
So, take the denominator once and add the numerators.
= (2 + 3)/7
= 5/7
Linda and Kemka together ate five-sevenths of a pizza.
7. Answer :
Amount of gas used by Mr. Alex to travel a total distance of 11 miles :
= 1/5 + 2/5
The fractions above have the same denominator. That is 5.
So, take the denominator once and add the numerators.
= (1 + 2)/5
= 3/5
Mr. Alex used three-fifths gallon of gas to travel a total distance of 11 miles.
8. Answer :
Total cost of one pencil and one pen :
= 2/9 + 5/9
The fractions above have the same denominator. That is 9.
So, take the denominator once and add the numerators.
= (2 + 5)/9
= 7/9
The total cost of one pencil and one pen is seven-ninths of a dollar.
