The squirrel jumps 4 steps at a time. Which numbers will the squirrel touch? How many times should the squirrel jump to reach 60?
(a) Numbers touched: The squirrel lands on multiples of 4. Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60...
(b) Jumps to reach 60: Number of jumps = 60 ÷ 4 = 15 ∴ The squirrel needs 15 jumps to reach 60.
Explanation
The chapter explains that when the squirrel jumps 4 steps at a time, it lands on multiples of 4. To find how many jumps are needed to reach 60, we divide 60 by 4. 60 ÷ 4 = 15, so the squirrel needs to make 15 jumps of 4 steps each to reach 60.
Solution Steps
Step 1: Identify that squirrel jumps 4 steps at a time, landing on multiples of 4
Step 2: List multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60...
Step 3: To find number of jumps to reach 60, divide 60 by 4
Step 4: 60 ÷ 4 = 15
Step 5: The squirrel needs 15 jumps to reach 60
