Final Answer:
20, 13, 18, 8
──────────────────────────────────────
Explanation:
Let’s go through each part one by one.
1.
Rachel and Mike:
- Rachel has 16 candies.
- Mike has 4 more than Rachel → 16 + 4 =
20.
So the top bar (Mike’s total) is 20. The question mark is the extra part: 20 − 16 =
4, but the blank box asks for Mike’s total, which is
20.
2.
Jacob and Mia:
- Jacob has 18 crayons.
- Mia has 5 fewer than Jacob → 18 − 5 =
13.
So Mia’s total is
13. The blank box is Mia’s total →
13.
3.
Maria and Oliver:
- Maria has 12 toys.
- Maria has 6 fewer than Oliver → so Oliver has 12 + 6 =
18.
The bottom bar shows Oliver’s total (the orange one), so the question mark is
18.
4.
Mia and Daniel:
- Daniel bought 15 items.
- Mia bought 7 fewer than Daniel → 15 − 7 =
8.
The blue bar is Mia’s amount, so the question mark is
8.
So the four missing numbers (in order from top to bottom) are:
20,
13,
18,
8.
