Question

Of the 627 coins in Jacob's coin jar, approximately 4/5 are silver, and approximately 1/10 of those coins that are sliver are dimes. Which of the following is the closest estimate for the number of dimes in Jacob's coin jar? 

 

F.50

G.100

H.125

J.250

K.500

Answer 1

There are 627 coins in the jar.

 

4/5 are silver

 

1/10 of silver are dimes

 

Total number of silver coins = 627 * 4/5 = 501.6

 

Dimes = number of * 1/10 => 501.6 * 1/10 = 50.16

 

Therefore the closet estimate is 50.

 

Hope this helps.

Answer 2

Laila, we just need to multiply.

 

627(4/5)(1/10) = 50
