Step-by-step explanation:
If you are dividing a fraction, the divisor will become it's reciprocal and the division sign will change to a multiplication sign.
Solution (a):
- 3 ÷ 1/4 = 12
- => 3 x 4 = 12
- => 12 = 12 [True]
Solution (b):
- 7 ÷ 1/2 = 1/14
- => 7 x 2 = 1/14
- => 14 ≠ 1/14 [False]
Solution (c):
- 1/5 ÷ 4 = 20
- => 1/5 x 1/4 = 20
- => 1/20 ≠ 20 [False]
Solution (d):
- 1/2 ÷ 5 = 5/2
- => 1/2 x 1/5 = 5/2
- => 1/10 ≠ 5/2 [False]
Solution (e):
- 1/7 ÷ 3 = 1/21
- => 1/7 x 1/3 = 1/21
- => 1/21 = 1/21 [True]
