Question #035a9

Answer 1

Another approach. Does not always work as easily as this. Depends on the question.

`0.364`

Explanation:

Suppose you hate decimals. Lets get rid of the decimal point at the beginning and put it back at the end.

`0.91` is the same as `91xx1/100`
`0.4` is the same as `4xx1/10`

Putting it all the above together we have: `4xx91xx1/100xx1/10`

`color(brown)("Dealing with just the numbers (no decimal place)")`

`color(white)(3)91`
`ul(color(white)(39)4)larr" Multiply"`
`364`

`color(brown)("Now we deal with the decimal")`

`1/100xx1/10=1/1000`

Putting it all together

`364xx1/1000= 0.364`
