Draw and label the coins from greatest to least value. Find the total value.

Question 1.

________

Answer: 22¢

1 dime = 10 cents

1 nickel = 5 cents Which means, 2 nickels = 5+5 = 10 cents and

2 pennies = 2 cents

Total : 10+10+2 = 22

Therefore, the total value f the coins = 22¢

Question 2.

_________

Answer: 75¢

1 quarter = 25 cents

Which means, 2 quarters = 25+25 = 50

1 dime = 10 cents

Which means, 2 dimes = 10+10 = 20

and 1 nickel = 5 cents

Total : 50+20+5 = 75

Therefore, total value of the coins = 75¢

**Problem Solving**

Solve. Write or draw to explain.

Question 3.

Rebecca has these coins. She spends 1 quarter. How much money does she have left?

Answer:

Firstly, Rebecca has 2 quarters , 1 dime, 1 nickel and 1 penny

1 quarter = 25 cents

Which means, 2 quarters = 25+25 = 50

1 dime = 10 cents

1 nickel = 5 cents and

1 penny = 1 cent

Total : 50+10+5+1 = 66¢

Given that,

she spends 1 quarter which means, 25 cents

Now, 66¢ – 25¢ = 41¢

Therefore, the leftover money is 41¢
