Carly paints magnets that she sells at craft fairs she can paint 12 magnets in 4 hours at this rate how many magnets can she paint in 2 hours? in 10 hours?

Answer 1

We know that she can paint 12 magnets in 4 hours.

We can calculate how many magnets she can paint in 2 hours by applying th rule of three:

`m=2\cdot(12)/(4)=(24)/(4)=6`

For 10 hours, we apply the same rule:

`m=10\cdot(12)/(4)=(120)/(4)=30`

Answer:

In 2 hours she can paint 6 magnets.

In 10 hours she can paint 30 magnets.
