Step-by-step Solution
We begin at the
START with:
>
1.38
---
####
1. 1.38 + 6.84
```
1.38
+6.84
------
8.22
```
✔ First circle:
8.22
---
####
2. 8.22 - 5.92
```
8.22
-5.92
-----
2.30
```
✔ Second circle:
2.30
---
####
3. 2.30 × 6.5
Let’s compute:
```
2.30 × 6.5 = ?
```
First, ignore decimals:
```
230 × 65 = ?
```
Break it down:
```
230 × 60 = 13,800
230 × 5 = 1,150
Total = 13,800 + 1,150 = 14,950
```
Now count decimal places:
- 2.30 has 2 decimal places
- 6.5 has 1 decimal place
→ Total: 3 decimal places
So:
```
14,950 → 14.950 → 14.95
```
✔ Third circle (down):
14.95
---
####
4. 14.95 + 13.7
```
14.95
+13.70
-------
28.65
```
✔ Fourth circle (right):
28.65
---
####
5. 28.65 ÷ 2.5
Let’s divide:
```
28.65 ÷ 2.5
```
To make it easier, multiply numerator and denominator by 10:
```
286.5 ÷ 25
```
Now divide:
```
25 × 11 = 275
286.5 - 275 = 11.5
Bring down: 11.5 → 115 tenths
25 × 4 = 100 → 115 - 100 = 15
Next: 150 hundredths → 25 × 6 = 150
```
So:
```
11.46
```
✔ Fifth circle (down):
11.46
---
####
6. 11.46 + 8.74
```
11.46
+8.74
------
20.20
```
✔ Sixth circle (left):
20.20
---
####
7. 20.20 × 5.3
Compute:
```
20.20 × 5.3
```
Break it down:
```
20.20 × 5 = 101.00
20.20 × 0.3 = 6.06
Add: 101.00 + 6.06 = 107.06
```
✔ Seventh circle (left):
107.06
---
####
8. 107.06 - 26.42
```
107.06
-26.42
-------
80.64
```
✔ Eighth circle (up):
80.64
---
####
9. 80.64 + 3.2
```
80.64
+3.20
------
83.84
```
✔ Ninth circle (left):
83.84
---
####
10. 83.84 × 8.6
Compute:
```
83.84 × 8.6
```
Break it down:
```
83.84 × 8 = 670.72
83.84 × 0.6 = 50.304
Add: 670.72 + 50.304 = 721.024
```
✔ Tenth circle (down):
721.024
---
####
11. 721.024 + 8.28
```
721.024
+ 8.280
--------
729.304
```
✔ Eleventh circle (down):
729.304
---
####
12. 729.304 + 1.5
```
729.304
+ 1.500
--------
730.804
```
✔ Twelfth circle (right):
730.804
---
####
13. 730.804 - 51.83
```
730.804
-51.830
--------
678.974
```
✔ Final circle (
FINISH):
678.974
---
✔ Final Answer:
The number in the
FINISH circle is
678.974
