To compare the numbers 0.69, 0.78, and \( \frac{3}{8} \), we first convert \( \frac{3}{8} \) to decimal form.
Calculating \( \frac{3}{8} \): \[ \frac{3}{8} = 0.375 \]
Now we have the following decimals to compare:
- 0.69
- 0.78
- 0.375
Arranging these from greatest to least:
- 0.78
- 0.69
- 0.375
So, the numbers from greatest to least are: 0.78, 0.69, 0.375.
