1. 3/4 or .75
You are looking for the sum
of the fractions, and you are given the values of the fractions,
although they have different denominators. What you need to do is
find a common denominator and add the two fractions
together.
2. 1, 3, 5, or 7
You know that –2 <
n < 10 and 2 <
m
< 10. Pick values for
n and
m to find the
minimum and maximum values for the range
n -
m.
3. 1/4 or .25
Because their sum is less than –6,
x and
y must
be negative integers that fall between –1 and –4.
4. x must be greater or equal to 0 and less than
5.
You are given two different inequalities, so solve each for
x to find the acceptable range of values.
