How do you change -1/2 into a decimal?

Answer 1

See explanation

A decimal is another way to write a fraction whose denominator is a power of #10#, so if you want to change a fraction to decimal first thing is to see if you can reduce or expand the fraction to get such denominator:
In this case to get a deniminator of #10# you only have to multiply numerator and denominator by #5#
#-1/2=-(1*color(red)(5))/(2*color(red)(5))=-5/10=-0.5#

This approach is not always effective, though; one way to determine if the decimal is finite for any given fraction is to compute the long division of the numerator and denominator. For instance:

2:3=0.666... 0

20/18

= 20 18

#-1/2=-0.5#

You can do this through division; #-1/2# is actually just a division problem:
#-1/2=-1÷2=-0.5#

Answer 3

To change -1/2 into a decimal, you divide the numerator (which is -1) by the denominator (which is 2):

-1 ÷ 2 = -0.5

So, -1/2 as a decimal is -0.5.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
