Answer:
<em>a:b:c=8:12:15</em>
Step-by-step explanation:
<u>Combined Ratio</u>
We are given the ratios:
a:b=2:3
b:c=4:5
The combined ratio a:b:c will include all three variables in one single expression.
Before finding it, we must have a common number for the common variable (b). Since b is 3 in the first ratio and 4 in the second ratio, we must equate both by finding the LCM of 3 and 4=12, thus both ratios will be amplified as follows:
a:b=2:3=(2*4):(3*4)=8:12
b:c=4:5=(4*3):(5*3)=12:15
Now there is a common factor in both ratios, we can combine them removing the common factor:
a:b:c=8:12:15

Ok so u wanna do the equation regularly and then u want to divide the top and bottom by 2 as much as u can but when u can’t divide one by 2 you can’t divide the other one either that’s when u stop
The 5 - number summary :
Min____ Q1 ___ median ____ Q3 ____ max
7 ______ 9 _____ 12 _______ 15 _____ 18
Answer:
Hence, from the 5 number summary, about 75% of sons have fewer than 15 stylist.
Step-by-step explanation:
Explaining the table :
Minimum number of stylist salons have = 7
Maximum number of stylist = 18
Q1 = first quartile, (25 /100) ;About 25% of salons have fewer Than 9 stylist
Q2 = second quartile or median ; About 50% of salons have fewer Than 12 stylist
Q3 gives the 75th percentile value.
Q3 = third quartile (75/100) ; About 75% of salons have fewer Than 15 stylist
