Question

Write –9 43/100 as a decimal number

Answer 1

`-9(43)/(100)`

Let's rewrite the mixed number as a fraction, using the following formula:

`a(b)/(c)=(a\cdot c+b)/(c)_{}`

So:

`-(9(43)/(100))=-((9\cdot100+43)/(100))=-((900+43)/(100))=-(943)/(100)`

To write -943/100 we can use long division, or since we are dividing by 100 we can simply move the decimal point two units to the left, so:

`-(943)/(100)=-9.43`

Answer:

-9.43
