LIKE FRACTIONS
:confetti_ball:
The group of two or more fractions that have exactly the same denominator are called like fractions :tada:
.
1. There are some groups of like fractions. Write three more like fractions in front of each group.
(i) 2/9, 5/9, 7/9, 9/9., 11/9…., …13/9., .
(ii) 1/7, 3/7, 4/7, 6/7., 7/7., …8/7., .
(iii) 3/8, 5/8, 7/8, 9/8., 11/9., 13/9…., .
(iii) 3/8, 5/8, 7/8, ………., ………., ………., .
(ii) 1/7, 3/7, 4/7, ………., ………., ………., .

Convert.
1. 113/12 = 9-5/12
2. 19/2 = 1-9/2
3. 36/10 = 3-3/5
4. 75/12 = 6-1/4
5. 50/8 = 6-1/4
UNLIKE FRACTIONS
:confetti_ball:
Unlike fractions are fractions that have different denominators

1. 3/8 + 1/4 = 5/8
2. 2/3 + 8/9 = 14/9
3. 5/6 + 1/4 = 14/9
4. 4/10 + 3/5 = 10/10 = 1
PROPER FRACTIONS
:confetti_ball:
Proper fractions are considered as those fractions in which the numerator is always less than the denominator.
