()Answer the question

**My question I got right:**

Fifty-six pounds in what percent of 140 pounds?

56 lbs. is _____% of 140 lbs.

140 is the

**whole**

56 is the

**part**

The ratio would be:

pounds given/total pounds = ?/100.

56 x 100/140 = 40%

56 lbs. is

**40%**of 140 lbs.

**My question that I got wrong is**:

Your employer has 600 business cars printed for you and you give away 280 of them. To the nearest hundredth, what percent of the cards is left?

____ cards were left.

**The wrong answer**:

600 is the total amount of cards (whole) and 280 is the part:

cards given/total cards = 280/600 = /100%. It would be 280 x 100/600 = 47.67%

**My mistake**was I didn't subtract 280 from 600 to get 320. Since, 280 is the cards given, I needed to find out the cards left. 600-280 = 320

**The right answer**:

cards left/total cards = 320/600 = /100%. It would be 320 x 100/600 = 53%

There are

**53%**of the cards left.
