Question

What is the value of `2 -: 3 4/5`?

Answer 1

`2 div 3 4/5 = color(green)(10/19)`

Explanation:

`3 4/5` can be written as an improper fraction `=19/5`

Division is the same as multiplication by the inverse.
`color(white)("XXX")kdiva =kxx1/a`
and
`color(white)("XXX")kdiv(a/b)=kxxb/a`

Therefore
`color(white)("XXX")2div3 4/5`
`color(white)("XXX")=2 div19/5`
`color(white)("XXX")=2 xx 5/19`
`color(white)("XXX")=10/19`
`color(white)("XXX")=10/19`
