Use PEMDAS. Extended answers at the very bottom.

Explanation:

Cool Math

We always want to follow the PEMDAS method.

Because there are no parentheses or exponents, we can skip the first two steps.

The next steps, Multiplication and Division, can be used.

#1/1# is a form of division, and can be simplified to become #1#.

We now have #1##/4 +1#

#1##/4# is another form of division, and can always look like #1/4#.

Now we have #1/4 +1#, where we just add the two together.

There are different ways to give your answer, whether you want a mixed number, improper fraction, or decimal form.

  1. Mixed number:
    #1 1/4#
  2. Improper fraction:
    #1# becomes #4/4#, and when added together becomes #5/4#.
  3. Decimal form:
    #1/4# is just #.25#, and becomes #1.25#.
