By definition, the ratio is the expression that would allow us to express the quotient of two numbers and/or any mathematical expressions. Let us take for example, numbers 4 and 5. The ratio between these values is 4/5.
The statement given above, "A ratio is a rate" is only sometimes true. This is only true when the unit of measurement of the denominator is in terms of time (seconds, minutes, hours, years, etc) because this would tell us how fast is something being done, consumed, etc. Example, the speed or rate of a car is 4 meters / 5 seconds.
The best thing to do us to find the difference between $150 and $100. The difference is $50. You've then got to divide $150/$50 and thus gives you 3.333, therefore, the percentage decrease is 33%
Hope this helps :)
Answer:
Step-by-step explanation:
The ratio of its areas is equal to
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
In this problem the scale factor is equal to the ratio 10:3
Let
z-------> the scale factor
so
z2=(10/3)2=100/9
Answer:
This cannot be simplified any further. That is the simplest you'll get.
