Problem 1 :
Find the value of :
1/2 + 1
Answer :
Multiply the denominator 2 and the whole number 1.
That is,
2 ⋅ 1 = 2
Now, take the denominator 2 as a common denominator for the sum (1 + 2).
(1 + 2)/2 = 3/2
Therefore,
1/2 + 1 = 3/2
Problem 2 :
Find the value of :
3/2 + 10
Answer :
Multiply the denominator 2 and the whole number 10.
That is,
2 ⋅ 10 = 20
Now, take the denominator 2 as a common denominator for the sum (3 + 20).
(3 + 20)/2 = 23/2
Therefore,
3/2 + 10 = 23/10
Problem 3 :
Find the value of :
5 + 2/3
Answer :
Multiply the denominator 3 and the whole number 5.
That is,
3 ⋅ 5 = 15
Now, take the denominator 2 as a common denominator for the sum (15 + 2).
(15 + 2)/3 = 17/3
There fore, we have
5 + 2/3 = 17/3
Problem 4 :
Find the value of :
7/8 + 9
Answer :
Multiply the denominator 8 and the whole number 9.
That is,
8 ⋅ 9 = 72
Now, take the denominator 8 as a common denominator for the sum (7 + 72).
(7 + 72)/8 = 79/3
There fore,
7/8 + 9 = 79/3
Problem 5 :
Find the value of :
7 + 5/8
Answer :
Multiply the denominator 8 and the whole number 7.
That is,
8 ⋅ 7 = 56
Now, take the denominator 8 as a common denominator for the sum (56 + 5)
(56 + 5)/8 = 61/8
There fore,
7 + 5/8 = 61/8
Problem 6 :
Find the value of :
1/5 + 2/5 + 7
Answer :
1/5 + 2/5 + 7
The two fractions above have the same denominator. That is 5.
So, take the denominator once and add the numerators.
= (1 + 2)/5 + 7
= 3/5 + 7
Multiply the denominator 5 and the whole number 7.
That is,
5 ⋅ 7 = 35
Now, take the denominator 5 as a common denominator for the sum (3 + 35).
(3 + 35)/5 = 38/5
There fore,
1/5 + 2/5 + 7 = 38/5
Problem 7 :
Find the value of :
3/4 + 5/6 + 2
Answer :
3/4 + 5/6 + 2
The two fractions above have different denominators.
Least common multiple of the denominators (4, 6) = 12.
In the two fractions 3/4 and 5/6, make each denominator as 12.
= 9/12 + 10/12 + 2
So, take the denominator once and add the numerators.
= (9 + 10)/12 + 2
= 19/12 + 7
Multiply the denominator 12 and the whole number 7.
That is,
12 ⋅ 7 = 84
Now, take the denominator 12 as a common denominator for the sum (19 + 84).
(19 + 84)/12 = 103/12
There fore,
3/4 + 5/6 + 2 = 103/12
