21 x 1/5 = 4 1/5 or 4.2
1/5 X 1/21 = 1/105
1/5 (one fifth)

12/3 * 21/5 = 5/3 * 11/5 = 11/3 = 32/3
One fifth times one sixth is calculated by multiplying the numerators and the denominators. So, ( \frac{1}{5} \times \frac{1}{6} = \frac{1 \times 1}{5 \times 6} = \frac{1}{30} ). Therefore, one fifth times one sixth equals one thirtieth.
1/5 X 1/21 = 1/105

It is 21/5.
12/3 * 21/5 = 5/3 * 11/5 = 11/3 = 32/3
One fifth times one sixth is calculated by multiplying the numerators and the denominators. So, ( \frac{1}{5} \times \frac{1}{6} = \frac{1 \times 1}{5 \times 6} = \frac{1}{30} ). Therefore, one fifth times one sixth equals one thirtieth.
21/5
One fifth times fifteen is calculated by multiplying 1/5 by 15. This equals 15/5, which simplifies to 3. Therefore, one fifth of fifteen is 3.
It is: 1/4 times 1/5 = 1/20
