In the first product the numerator of the fraction is greater than the denominator, therefore the fraction is greater than 1. On the other hand in the second product the numerator of the fraction is smaller than the denominator, therefore the fraction is smaller than one. That means the first product is greater than the second one.
Answer: ![4.5\ meters](https://tex.z-dn.net/?f=4.5%5C%20meters)
Step-by-step explanation:
Using the data given in the exercise, we can draw the diagram attached, where "h" is the height of the building reached by the top of the ladder.
Notice that there are two similar triangles.
So, you can set up the following proportion:
![\frac{1.8}{1.2}=\frac{h}{(1.2+1.8)}](https://tex.z-dn.net/?f=%5Cfrac%7B1.8%7D%7B1.2%7D%3D%5Cfrac%7Bh%7D%7B%281.2%2B1.8%29%7D)
Finally, in order to calculate the height on the building reached by the top of the ladder, you must solve for "h".
Therefore, the value of "h" is :
![\frac{1.8}{1.2}=\frac{h}{3}\\\\(3)(\frac{1.8}{1.2})=h\\\\\frac{5.4}{1.2}=h\\\\h=4.5](https://tex.z-dn.net/?f=%5Cfrac%7B1.8%7D%7B1.2%7D%3D%5Cfrac%7Bh%7D%7B3%7D%5C%5C%5C%5C%283%29%28%5Cfrac%7B1.8%7D%7B1.2%7D%29%3Dh%5C%5C%5C%5C%5Cfrac%7B5.4%7D%7B1.2%7D%3Dh%5C%5C%5C%5Ch%3D4.5)
The slope of the line is -(1/2)
Because the ratio of women to children is 10:1, double the ratio of men to women so the women are both 10:
Men to women becomes 8:10
Now total the 3 ratios: 8 for men, 10, for women and 9 for children:
8 + 10 + 9 = 27
Divide total people by that number:
270/27 = 10
Multiply 10 by each ratio:
Men = 8 * 10 = 80
Women = 10 * 10 = 100
Children = 9 *10 = 90
There is 80 men.
