Fractions are very useful in measuring. Example. I buy enough weed killer for 1000 sq. ft. of lawn because the store was out of the bottle for 500 sq. ft. SO...... I only need 1/2 (half) the bottle because I only have 1/2 the yard . Another example. Polls indicate two out of three people in the US will vote for John McCain for president. There are 3 million registered voters. How many votes will he get? And, if 2 out of three will vote for him, how many will Obama get? If 2 out of 3 ....(2/3)... vote for McCain, and there are 3 million voters, 2/3 or 2 million will vote for McCain, leaving one out of three (1/3) for Obama, which is one million.
