Answer:
2:2
Step-by-step explanation:
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
Answer:
16/3 is a reduced answer to 32/x
To find out what x equals you would think 16 times what equals 32
32/16=2
So now you would take 3*2 to get 6 for x
16/3 is a reduced answer to 32/6

Hello! answer: 432
Step-by-step explanation:
12 × 8 = 96
12 × 8 = 96
12 × 6 = 72
12 × 6 = 72
8 × 6 = 48
8 × 6 = 48
Then you add them all up so...
96 + 96 + 72 + 72 + 48 + 48 = 432 therefore the surface area is 432 hope that helps!
260 seats in economy class, 100 in business class
The ratio of economy class to business class is 13:5
13+5 = 18 (total seats in the ratio)
360/18 = 20 (to see how many multiples of the ratio there are)
20*13 economy = 260 economy
20*5 business = 100 business
