Answer:
Explanation:
Count by 10s:
1 + 10 = 10.
10 + 10 = 20.
20 + 10 = 30.
30 + 10 = 40.
40 + 10 = 50.
Question 2.
Write the total amount of money for each set:
a.
_____________ ¢
Answer:
= 24 ¢.
Explanation:
Number of dimes = 2 × 10 cents = 20 cents.
Number of pennies = 4 × 1 cent = 4 cents.
Total amount = Number of dimes + Number of pennies
= 20 cents + 4 cents
= 24 cents.
b.
_____________ ¢
Answer:
= 41 ¢.
Explanation:
Number of dimes = 4 × 10 cents = 40 cents.
Number of pennies = 1 × 1 cent = 1 cents.
Total amount = Number of dimes + Number of pennies
= 40 cents + 1 cents
= 41 cents.
c.
_____________ ¢
Answer:
= 15 ¢.
Explanation:
Number of dimes = 1 × 10 cents = 10 cents.
Number of pennies = 5 × 1 cent = 5 cents.
Total amount = Number of dimes + Number of pennies
= 10 cents + 5 cents
= 15 cents.
d.
_____________ ¢
Answer:
= 33 ¢.
Explanation:
Number of dimes = 3 × 10 cents = 30 cents.
Number of pennies = 3 × 1 cent = 3 cents.
Total amount = Number of dimes + Number of pennies
= 30 cents + 3 cents
= 33 cents.
e.
