Maria bought 5 cans of tennis balls. Each can contained 3 tennis balls. How many tennis balls did Maria buy altogether?
3 + 3 + 3 + 3 + 3 =
To find out how many tennis balls Maria bought altogether, we need to multiply the number of cans by the number of tennis balls in each can.
Maria bought 5 cans of tennis balls, and each can contained 3 tennis balls. So, we can multiply 5 by 3 as follows:
5 (cans) x 3 (tennis balls per can) = 15 tennis balls
Therefore, Maria bought a total of 15 tennis balls altogether.
