Answer:
3 3/16
Step-by-step explanation:
Conversion a mixed number 8 1/2
to a improper fraction: 8 1/2=8×2+1/2=16+1/2=17/2
To find a new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2×3/3= 6/
3
b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8
c) Write a previous answer (new numerator 8) over the denominator 3.
Two and two thirds is eight thirds
Divide: 17/2×8/3=17/2×3/8=17×3/2×8= 51/
16
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 8/3 is 3/8) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seventeen halves divided by eight thirds = fifty-one sixteenths.

Answer:
Rate
Step-by-step explanation:
Rate is basically also a ratio. but it is the comparing of two different quantities with different units.
As ratio is comparing of same or identical quantities thus it has no units. But on the other hand as rate is the comparison of different quantities, thus it has units.
for example:
When i compare two quantities, 1st is a distance quantity and 2nd is a time quantity i.e.
20 meters : 15 seconds
thus the lowest form of this relationship will be:
4 meters : 3 seconds
when i write it in Decimal form it becomes :
Ans : 1.33 meters/second (Distance per unit time)
As this ratio have remaining units thus it is referred to as "RATE".
