One way to compare quantities is with fractional numbers that represent quantities using divided numbers.
<h3>What is a fraction?</h3>
Fractional number is a mathematical concept that refers to a quantity divided by another quantity. Common fractions are made up of: numerator, denominator and dividing line between them (horizontal or oblique bar).
- The denominator "b" expresses the number of equal parts that represent the unit.
- The numerator "a" indicates how many of them are taken.
Some examples of fractional numbers are:

Answer:
sorry im middle school we can still hang though
Step-by-step explanation:
(a) there are 8C2 = 28 ways of picking 2 girls from 8
And there are 21C4 = 5985 ways of picking 4 boys
Required number of ways for 2g / 4b = 28 * 5985 = 167,580
(b) at least 2 girls means combinations of 2g/4b , 3g,3b , 4g/2b , 5g 1b or
6 girls.
2g/4b = 167,580 ways
3g/3b = 8C3 * 21C3 = 56 * 1330 = 74,480
4g/2b = 8C4* 21C2 = 70 * 210 = 14,700
5g 1b = 8C5* 21 = 56*21 = 1176
6 girls = 8C6 = 28
adding these up we get the answer to (b) which is 257,964
Yes it does have to be parallel or else it would not be a rectangle.So it is true.
Hope this helped! :)
Answer:
8/9
Step-by-step explanation:
The equation to find a slope is y2-y1/x2-x1=m. (m is the slope)
174-166/173-164
8/9
So the slope is 8/9.
