-12.7

Express it as:


-(12.7)/(1)

Multiply by 10 the numerator and the denominator:


-(12.7)/(1)*(10)/(10)=-(127)/(10)

so:


-12.7=-(127)/(10)

----------------------

For a mixed number, we can use the following formula:


a(b)/(c)=(ac+b)/(c)

So:


11(1)/(4)=(11\cdot4+1)/(4)=(44+1)/(4)=(45)/(4)
