Let’s look at the ratio table step by step.
We have two columns:
a and
b.
The values in column
a are:
1, 2, 3, 6, 9
The values in column
b are:
4, 8, 12, 24, 36
Now let’s check the relationships shown with arrows:
- From
a = 1 to a = 2: multiply by 2 → 1 × 2 = 2
✔
- From
a = 2 to a = 3: wait — that’s not multiplying by 3. Actually, looking again, the arrow says “x3” from 1 to 3? Let me recheck.
Actually, the arrows on the left side (for column a) show:
- From 1 → 2: labeled “x2” → 1 × 2 = 2
✔
- From 1 → 3: labeled “x3” → 1 × 3 = 3
✔
Then it continues down: 6 and 9 — which are 1×6 and 1×9.
On the right side (column b):
- From 4 → 8: x2 → 4 × 2 = 8
✔
- From 4 → 12: x3 → 4 × 3 = 12
✔
- From 4 → 24: x6 → 4 × 6 = 24
✔
- From 4 → 36: x9 → 4 × 9 = 36
✔
So actually, each value in column
b is just
4 times the corresponding value in column
a.
Check:
- a=1 → b=4 → 1×4=4
✔
- a=2 → b=8 → 2×4=8
✔
- a=3 → b=12 → 3×4=12
✔
- a=6 → b=24 → 6×4=24
✔
- a=9 → b=36 → 9×4=36
✔
Perfect! So the rule is:
b = a × 4
That means for any number in column a, you multiply by 4 to get the matching number in column b.
Final Answer:
b = a × 4
