I'd like to multiply Ether by a decimal (a proportion, e.g. 0.05). I've got:

```
ufixed proportion; // What type should proportion be?
function functionName() {
var Ether = msg.value; // (in units of wei)
var proportionOfEther = Ether * proportion
...
```

My Solidity linter is saying that `*`

is not compatible with uint256 (the Ether) and ufixed128x128 (the proportion).

## Best Answer

Instead of multiplying by a decimal, multiply and divide by integers.

i.e.

`(Ether * 5)/100`
