What is the multiplier for 5/7=30/42 please help

horsena [70]

Answer:

The multiplier is 1

specifically:

$\frac{6}{6}$

Step-by-step explanation:

Let the multiplier be k

Then,

$\frac{5}{7} \times k = \frac{30}{42}$

We multiply both sides by 7/5

$\frac{7}{5} \times \frac{5}{7} k = \frac{30}{42} \times \frac{7}{5}$

$k = \frac{6}{6}$

We can simplify this further to get 1.

This implies that:

$\frac{5}{7} \times \frac{6}{6} = \frac{30}{42}$

Hence the multiplier is 1.

If it took one hour to complete a card game, we can tell that the average play time varies around that time.

So only one game can be completed in one hour.

Hope it helped,

Happy homework/ study/ exam!
