Maggie's goal was to collect 60 canned goods for a food drive she actually collected 81% of her goal did Maggie reach

This didn't really state what you wanted to find. But I'm assuming you're trying to find how much of the 60 cans she sold if you collected 81%.

In this case your equation would be 81% of 60.

The first thing you do is convert 81% to a decimal by moving the decimal place 2 spaces to the left. So you get. 81 of 60

"of" states multiplication, so. 81 times 60 is 48.6

So Maggie collected 48.6 cans out of 60
