Answer:
a) LCM of denominators(7, 4) =28
1/7 = 1×4/7×4 = 4/28
1/4 = 1×7/4×7 = 7/28
Since, 4/28 < 7/28
.•. 1/7 < 1/4.
b) LCM of 5,7 = 35
3/5 = 3×7/5×7 = 21/35
3/7 = 3×5/7×5 = 15/35
Since, 21/35 > 15/35
.•. 3/5 > 3/7.
Step-by-step explanation:
1. Since the fractions are unlike, first find the LCM of the denominators.
2. Multiply the LCM with the denominators to change them into like fractions.
3. Now compare the like fractions.
