Ratios & Rates
For this assignment, we have to blog about Rates & Ratios. The difference between a rate and a ratio is this:
RATE- ratio comparing two different units.
RATIO- comparison using division.
An example of a RATIO is 2:3 people bet that Lucky would win the race.
An example of a RATE is the car drove 35mph for 6 hrs. This is a RATE because it's comparing two different units(miles per hour vs. hours)
UNIT RATE is a rate with a denominator of one. An example of a UNIT RATE would be the runner ran 2 miles in 1 hour. This is a UNIT RATE because the denominator is one.
UNIT ANALYSIS is like converting seconds into minutes or minutes into hours. Here's a website that will help give you examples of UNIT ANALYSIS:
