Final answer:
Lukas's dad is 5 times older than Lukas. To find this, divide the dad's age (40 years) by Lukas's age (8 years).
Step-by-step explanation:
To solve the mathematical problem completely, we need to calculate how many times older Lukas's dad is compared to Lukas. The question asks us to find the ratio of Lukas's dad's age to Lukas's age.
Lukas's age = 8 years old
Lukas's dad's age = 40 years old
To find out how many times older Lukas's dad is, we divide the dad's age by Lukas's age:
Ratio = Lukas's dad's age ÷ Lukas's age
= 40 ÷ 8
= 5
Therefore, Lukas's dad is 5 times older than Lukas.
