Example Question #4 : Other Data Calculations
A new donut shop is opening! As an introductory offer they are selling donuts for a dozen. John has . How many donuts can he buy?
To find out how many donuts John can buy we first need to see how many dozens he can buy with his $18.

Therefore, John can buy 72 donuts.
Example Question #5 : Other Data Calculations
Country A has the largest population on Earth, with billion people. Country B is next with billion people. How many more people does Country A have than Country B?
To find how many more people Country A has than B we need to subtract the number of people in Country B from that in Country A.
From here we will convert the units from billion to million.
0.3 billion is equivalent to 300,000,000
