Last week, our word problems gave kids such great practice in figuring out “how much or how many” of a given thing, we decided to go another round!
Excellent! Are you ready to check your child’s answer? Look below to see if their solution matches ours.
Answer: 9 nickels
Solution: Since a quarter is worth 25¢ and a dime is worth 10¢, Lauren has 25¢ + 10¢ + 10¢ + 10¢ = 55¢. Since she has $1.00 worth of coins, that means she has 100¢ – 55¢ = 45¢ in nickels. It takes 9 nickels to make 45¢. So, Lauren has 9 nickels.
Answer: 56 tickets
Solution: The scout troop made $10.00 × 12 = $120.00. Since they made a total of $400.00, they made $400.00 – $120.00 = $280.00 from the sale of child tickets. Since they sold child tickets for $5.00 each, the number of child tickets they sold was $280.00 ÷ $5.00 = 56 tickets.
Answer: 63/4 pounds of food
Solution: Since 3 pounds of dog food is enough to be divided among 8 dogs, each dog eats 3/8 of a pound of dog food. So, 18 dogs will need 3/8 × 18 = 54/8 = 63/4 pounds of food.
High School and Up:
Answer: 1 hour and 12 minutes
Solution: James can paint 1 fence in 2 hours, so his rate is 1 fence/2 hours. Jessie can paint 1 fence in 3 hours, so her rate is 1 fence/3 hours. If we add their rates together, we get the rate at which they can paint a fence if they work together: 1 fence/2 hours + 1 fence/3 hours = 1 fence/x hours. If we solve for x, we get x = 6/5 = 11/5. So, James and Jessie can paint a fence together in 11/5 hours, or 1 hour and 12 minutes.
