Question

Of the 627 coins in Jacob's coin jar, approximately 4 5 are silver, and approximately of those coins 10 that are silver 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

To find the estimated number of dimes in Jacob's coin jar, multiply the total number of coins (627) by 4/5 to find the number of silver coins, then multiply this result by 1/10. The closest estimate is 50 dimes. Therefore correct option is F

Step-by-step explanation:

The question asks us to find the closest estimate for the number of dimes in Jacob's coin jar. There are 627 coins in total, and approximately 4/5 of these are silver. Then, out of the silver coins, 1/10 are dimes. To solve the problem

1. Calculate the number of silver coins by multiplying 627 by 4/5.
2. After finding the number of silver coins, calculate the number of silver dimes by multiplying the number of silver coins by 1/10.

Step 1: 627 * 4/5 = 501.6, which we approximate to 502 silver coins.

Step 2: 502 * 1/10 = 50.2, which we approximate to 50 dimes.

Therefore, the closest estimate for the number of dimes in Jacob's coin jar is 50.
