Mrs. West went to the furniture store and found a crate containing 142 large coins. If the coins weighed 24,783 ounces, how much did each coin weigh?

A) 590 75/142

B) 174 75/142

C) 174 75/24,783

D) 142 75/174

174 75/142

B

Step-by-step explanation:

Formula

1 coin = Total Mass / number of coins

Givens

Total mass 24783 Ounces (That's awfully heavy. You sure you don't mean grams?)

142 coins

Solution

1 coin = 24783 / 142

1 coin = 174.528169

This is multiple choice so you only have to try one thing. What is 75/142? It turns out that the result is 75/142

75/142 = 0.528169

Another way to do it is to figure out what 174 in whole numbers would weigh:

174 * 142 = 24708

What number is left over? 24783 - 24708 = 75

So the fractional part is 75/142
