Question #a9a67

Answer 1

`79div4.5=color(blue)(17.555bar5)`

Explanation:

While this can be done directly, it is probably easier to first multiply both the dividend and the division by `2` to avoid the fractional component.

`79 div 4.5`
`color(white)("XXX")=(79xx2) div (4.5xx2)`

`color(white)("XXX")=158 div 9`

(then either by inspection or long division)
`color(white)("XXX")=17 5/9`

...or as a repeating decimal
`color(white)("XXX")=17.55bar5`
