write about it.

1. malachi has 6 nickels and 2 dimes. noah has 5 dimes. who has more money? explain.

Explanation:

Step1: Recall coin - values

A penny is worth 1 cent, a nickel is worth 5 cents, and a dime is worth 10 cents.

Step2: Solve problem 3

7 dimes are worth \(7\times10 = 70\) cents and 3 pennies are worth \(3\times1=3\) cents. The total is \(70 + 3=73\) cents.

Step3: Solve problem 4

4 dimes are worth \(4\times10 = 40\) cents, 1 nickel is worth 5 cents, and 4 pennies are worth \(4\times1 = 4\) cents. The total is \(40+5 + 4=49\) cents.

Step4: Solve problem 5

3 dimes are worth \(3\times10 = 30\) cents, 1 nickel is worth 5 cents, and 3 pennies are worth \(3\times1=3\) cents. The total is \(30 + 5+3=38\) cents.

Step5: Solve problem 6

Justin starts with 30 cents and ends with 45 cents. The amount he found is \(45 - 30=15\) cents. A dime (10 cents) and a nickel (5 cents) make 15 cents.

Step6: Solve problem 7

Malachi: 6 nickels are worth \(6\times5 = 30\) cents and 2 dimes are worth \(2\times10=20\) cents. So Malachi has \(30 + 20=50\) cents. Noah: 5 dimes are worth \(5\times10 = 50\) cents. They have the same amount of money.

Answer:

1. 73 cents
2. 49 cents
3. 38 cents
4. dime, nickel
5. They have the same amount of money.
