Question

Marco is 24 and Matteo is two time less than Marco
How old is Matteo?

Answer 1

You need to find what relation do Marco’s and Matteo’s ages have.
If x=Matteo’s age, you can write
24/2=x because two times less means you have to divide by 2
So then you just have to find x
24/2=x
12=x
Matteo is 12
