Explanation:
Let’s solve each problem one by one.
Problem 1:
There were 46 balls total.
20 were soccer balls, 15 were basketballs.
So soccer + basketball = 20 + 15 = 35 balls.
The rest are tennis balls: 46 − 35 =
11 tennis balls.
Problem 2:
30 children lined up.
9 joined → now 30 + 9 = 39.
Then 4 left → 39 − 4 =
35 children left in line.
Problem 3:
Dad caught 22 fish in the morning.
He threw back 5 → 22 − 5 = 17 kept.
Then caught 12 more in afternoon → 17 + 12 =
29 fish total.
Problem 4:
Saw 32 animals total: 12 dogs + 15 squirrels + ? frogs.
12 + 15 = 27.
So frogs = 32 − 27 =
5 frogs.
But the question asks: *How many were tennis balls?*
That’s the first problem — answer is
11.
