To determine which of the given decimals is the biggest, let's compare each of them step-by-step:
(a) 0.04: This decimal is relatively small as it represents four hundredths.
(b) 0.004: This decimal is even smaller, representing four thousandths, which is one-tenth of 0.04.
(c) 0.0004: This decimal is much smaller, representing four ten-thousandths, which is one-tenth of 0.004.
(d) 0.4: This decimal is larger, representing four tenths. It is ten times greater than 0.04.
(e) 110: This is a whole number and significantly larger compared to any of the other decimal numbers provided.
After comparing each of the decimals and the whole number, we can see that:
- 110 is the largest number when compared to the given decimals.
Therefore, the biggest decimal is:
```
