Question

I need help with this because I tried and it never worked out.

Answer 1

First let's factor 9

Therefore we can write 9 as

$9=3\times3$

But if we want with 1 as a factor we must write is just like

$9=9\times1$

Which seems trivial, because

$180000\div9\div1$

Is true, therefore, if we want 1 included in the division the answer would be

$180000\div9\div1$
