The exact name of the postulate isn't coming to mind, but it's the postulate that any three points that are not on the same line will form a unique plane. A plane in mathematics is a flat surface that extends in all directions.

3÷ 1/4. 7÷ 1/2. 1/5÷ 1/20. 1/2÷ 1/10. 1/7÷ 3.. help me solve all these please.

Nina [5.8K]

Answer:

Step-by-step explanation:

Use KCF method for fraction division.

Keep the first fraction

Change the operation to multiplication

Flip the second fraction.

1) 3÷ (1/4) = $3*\frac{4}{1}= 12$

2) 7 ÷ (1/2) = $7 * \frac{2}{1}=14$

3) (1/5) ÷ (1/20) = $\frac{1}{5}*\frac{20}{1}=4$

4) (1/2) ÷ (1/10) = $\frac{1}{2}*\frac{10}{1}=5$

5) (1/7) ÷ 3 = $\frac{1}{7}*\frac{1}{3}=\frac{1}{21}$
