jonah's sister is 10 years old. Jonah is 8 years younger than twice his sister age
(10 * 2) - 8 = ?
To find Jonah's age, we will use the information provided: Jonah's sister is 10 years old and Jonah is 8 years younger than twice his sister's age.
1. Let's find twice Jonah's sister's age:
Twice Jonah's sister's age = 2 * 10 = 20
2. Jonah is 8 years younger than twice his sister's age:
Jonah's age = 20 - 8 = 12
Therefore, Jonah is 12 years old.
To find Jonah's age, we need to first determine twice his sister's age and then subtract 8 from that.
Twice his sister's age: 10 x 2 = 20
Jonah's age: 20 - 8 = 12
Therefore, Jonah is 12 years old.
