$0.4 \div 0.008 = 50$ $0.4-:0.008= 50$

Explanation:

Given: $0.4 \div 0.008$ $" "0.4-:0.008$

Write as $\frac{0.4}{0.008}$ $" "color(blue)(0.4/0.008)$

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To get rid of the decimals multiply by 1 but in the form of

$1 = \frac{1000}{1000}$ $" "1=color(brown)(1000/1000)$ giving
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

$\frac{0.4 \times 1000}{0.008 \times 1000} = \frac{400}{8}$ $" "color(blue)((0.4color(brown)(xx1000))/(0.008color(brown)(xx1000)))color(green)( = 400/8)$

Lets split (partition) the number to make it easier to work out in our heads

400 can be slit (partitioned) into $10 \times 40$ $10xx40$

So we can rewrite $\frac{400}{8}$ $color(green)(400/8)$ as

$10 \times \frac{40}{8}$ $" "color(green)( 10 xx 40/8)$

But $5 \times 8 = 40 that is: 40 \div 8 = 5$ $5xx8 =40" that is: "40-:8=5$ so we end up with

$10 \times 5 = 50$ $" " color(blue)(color(green)(10 xx5) = 50)$
