Answer :

Let's solve each part of the problem step-by-step to find the dividend.

### Part (a)
To find the dividend where the equation is given as:
[tex]\[ \frac{\text{dividend}}{8} = 8 \][/tex]

To isolate the dividend, you can multiply both sides of the equation by 8:
[tex]\[ \text{dividend} = 8 \times 8 \][/tex]

[tex]\[ \text{dividend} = 64 \][/tex]

So, the dividend for part (a) is [tex]\(\boxed{64}\)[/tex].

### Part (c)
To find the dividend where the equation is given as:
[tex]\[ \frac{\text{dividend}}{3} = 8 \][/tex]

Again, isolate the dividend by multiplying both sides by 3:
[tex]\[ \text{dividend} = 8 \times 3 \][/tex]

[tex]\[ \text{dividend} = 24 \][/tex]

So, the dividend for part (c) is [tex]\(\boxed{24}\)[/tex].

### Part (e)
To find the dividend where the equation is given as:
[tex]\[ \frac{\text{dividend}}{6} = 5 \][/tex]

Isolate the dividend by multiplying both sides by 6:
[tex]\[ \text{dividend} = 5 \times 6 \][/tex]

[tex]\[ \text{dividend} = 30 \][/tex]

So, the dividend for part (e) is [tex]\(\boxed{30}\)[/tex].

Summarizing the results:
- Part (a) dividend is [tex]\(64\)[/tex].
- Part (c) dividend is [tex]\(24\)[/tex].
- Part (e) dividend is [tex]\(30\)[/tex].
