2. Montell opened up 17 stores in every city if there is 9 cities
and there are 153 stores are in each city how many stores
are in one city?
Step 1:set up your proportions
with the information from the problem.
153
9*153=17x
1377=17x
x=81
/17/17
stores
cities
17
9 x
Step 2:then you cross
multiply and when you have the
answer alone with a variable.
Step 3:then you divide both
sides by the number that is with the
variable then you will have the answer.
3. 45% of what is 9?
Step 1:set up
proportions
9
100*9=45x
900=45x
X=20
/45/45
45
100 x
Step 2:then you cross multiply and
