Question

Martina's penny bank is 2/9 full. After she adds
480 pennies, it is 2/3
full. How many pennies can Martina's bank hold?

Answer 1

Okay. The 480 pennies is equal to 4/9ths full
Can you try to use that to tell me how much one ninth is?

Answer 2

0.4

Answer 3

Try multiplying the 480 pennies by 4/9ths. That will give you 1/9th of the total

Answer 4

Once you do that, you can multiply whatever number you get by nine to get the total

Answer 5

640

Answer 6

5760

Answer 7

Not quite.
480 x 4/9 is 213.33

Answer 8

so that'd be the answer?

Answer 9

When you multiply by a fraction, the number will be smaller than the original. This isn't done yet because you need to multiply 213.33 by 9 since 213.33 is what we found to be 1/9th of the total

Answer 10

1919.97

Answer 11

Yeah. The actual number is 1920 since we rounded a little. Great job.
