Question

Jessa has $23 that she wants to divide equally between her 5 children. How much money will each receive?

Answer 1

$ 4,60

Explanation:

Split the $23 into `$20+$3`

So we have: `($20)/5+($3)/5`

`($20)/5 = $4`

`($3)/5 =[($3)/5color(red)(xx1)]=[($3)/5color(red)(xx2/2)]=($6)/10=$0.6`

Add this and the result is

$4.60

Answer 2

Sow you a sort of cheat method.

`$23-:5=$4.60`

Explanation:

Using the principle that dividing by 10 is simpler

Divide by 5 is the same as multiply by `1/5`

But `1/5` is double `1/10`

So we have:

`2xx($23xx1/10) = 2xx(2.3) = 4.6`

Thus `$23-:5=$4.60`
