Question 5.
Lena has 3 dimes and 3 pennies. Draw how many tens and ones. What is the total value of Lena’s coins?
____ ¢ Lena had 33 coins.

Explanation:
Here, Lena has 3 dimes and 3 pennies. As 1 dime is 10 cents so 3 dimes are 3×10 which is 30 cents and 1 penny is 1 cent, so 3 pennies is 3 cents. So the total number of coins does Lena had is 30 cents+ 3 cents which is 33 coins. Question 6.
Find the total value of the coins.
______ The total value of the coins is 61 cents.

Explanation:
As there is 1 penny, 3 dimes, 1 quarter, and 1 nickel. So (1×1)+(3×10)+(1×25)+(1×5) which is 1+30+25+5 = 61 cents. So the total value of the coins is 61 cents.
