Some fridge magnets are put in a bag. There are 36 small magnets and the rest are large. Some magnets are red, and the rest are white.

- The number of large magnets is [tex]\(\frac{1}{2}\)[/tex] the number of small magnets.
- There are 5 times as many white magnets as red magnets.
- There are 8 large red magnets.

Work out how many small white magnets are in the bag.

You may use the two-way table to help you.

To find the number of small white magnets, let's go through the problem step-by-step using the given information and forming equations.

1. Number of Magnets:
- There are 36 small magnets.
- The number of large magnets is [tex]\(\frac{1}{2}\)[/tex] the number of small magnets.

2. Calculation for Large Magnets:
[tex]\[ \text{Number of large magnets} = \frac{1}{2} \times 36 = 18 \][/tex]

3. Distribution Based on Color:
- There are 5 times as many white magnets as red magnets in total.
- There are 8 large red magnets.

4. Calculation for Large White Magnets:
[tex]\[ \text{Total large magnets} = 18 \][/tex]
[tex]\[ \text{Large white magnets} = 18 - 8 = 10 \][/tex]

5. Total Red Magnets:
- Let [tex]\(r\)[/tex] represent the total number of red magnets.
- Let [tex]\(w\)[/tex] (which is 5 times [tex]\(r\)[/tex]) represent the total number of white magnets.

6. Forming the Equation:
- From the problem: [tex]\(w = 5r\)[/tex]
- The number of red magnets:
[tex]\[ r = \text{small red magnets} + \text{large red magnets} \][/tex]
- The number of white magnets:
[tex]\[ w = \text{small white magnets} + \text{large white magnets} \][/tex]
- Therefore:
[tex]\[ w = \text{small white magnets} + 10 \][/tex]

7. Solving for Red and White Magnets:
[tex]\[ r = 8 + \text{small red magnets} \][/tex]
[tex]\[ w = 5r \Rightarrow w = 5(8 + \text{small red magnets}) \][/tex]

8. Total Small Magnets:
[tex]\[ 36 = \text{small red magnets} + \text{small white magnets} \][/tex]

9. Forming Equations:
\begin{align}
r &= 8 + \text{small red magnets} \\
5r &= \text{small white magnets} + 10 \\
\end{align
}

10. Expressing Variables:
[tex]\[ \text{small white magnets} = 5r - 10 \][/tex]

11. Solving the System:
[tex]\[ r = 8 + \text{small red magnets} \][/tex]
[tex]\[ 36 = \text{small red magnets} + \text{small white magnets} \][/tex]

12. Substitute [tex]\(r\)[/tex] in [tex]\(36 = \text{small red magnets} + 5r - 10\)[/tex]:
[tex]\[ r = -10 \][/tex]

13. Calculating Small Magnets:
[tex]\( \text{small red magnets} + \text{small white magnets} = 36 \)[/tex]
[tex]\( \text{small white magnets} = -60 \)[/tex]

So, the number of small white magnets is [tex]\(-60\)[/tex].

Thus, following these steps given in the problem, we determine that such a scenario is numerically not possible because the number of magnets should be a positive number, indicating perhaps some assumptions or given constraints need revisiting, but based on the given data the solution stays as described above.
