Amy's penny bank is 1/2 full. after she adds 360 pennies, it is 5/6 full. how many pennies can amy's bank hold?

1,080 Pennies

Step-by-step explanation:

This question is fairly simple, you just have to simplify it. You are starting at already half-full, so you can keep that 1/2 in mind. Then, she adds 360 pennies to get 5/6. If you convert 1/2 into 3/6, you can see that 360 pennies fills 2/6 of the piggy bank. So now you can solve two different ways. The first, you can take 360 and multiply it by 3 to get the amount that can fit in the piggy bank, because 2 * 3 = 6 and that would make it 6/6, or 1. The other way would be to divide 360 by 2 to get 1/6 of the piggy bank, or 180. Then you can multiply 180 by 6 to get the entire amount.

Hope this helped ^-^

1.5 hours

Step-by-step explanation:

we know that

1) Martha can paint a room in 2 hours

so

Martha can paint the 100% of the room in 2 hours

Find out what percentage of the room she can paint in an hour

using proportion

2) Jamie can paint a room in 6 hours

so

Jaimie can paint the 100% of the room in 6 hours

Find out what percentage of the room she can paint in an hour

using proportion

3) In one hour Martha and Jamie can paint

so

using proportion

Find out how long will it take them to paint the 100% room together
