Answer:
The number of 1/5 liter glasses that Lin can fill is ![7\frac{1}{2}](https://tex.z-dn.net/?f=7%5Cfrac%7B1%7D%7B2%7D)
Step-by-step explanation:
we know that
To find out how many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water, divided 1 1/2 by 1/5
so
![1\frac{1}{2} :\frac{1}{5}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B2%7D%20%3A%5Cfrac%7B1%7D%7B5%7D)
Convert mixed number to an improper fraction
![1\frac{1}{2}=1+\frac{1}{2}=1\frac{1*2+1}{2}=\frac{3}{2}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B2%7D%3D1%2B%5Cfrac%7B1%7D%7B2%7D%3D1%5Cfrac%7B1%2A2%2B1%7D%7B2%7D%3D%5Cfrac%7B3%7D%7B2%7D)
substitute
![\frac{3}{2} :\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%20%3A%5Cfrac%7B1%7D%7B5%7D)
Multiply in cross
![\frac{5*3}{2*1}=\frac{15}{2}=7.5](https://tex.z-dn.net/?f=%5Cfrac%7B5%2A3%7D%7B2%2A1%7D%3D%5Cfrac%7B15%7D%7B2%7D%3D7.5)
Convert to mixed number
![7.5=7+\frac{1}{2}=7\frac{1}{2}](https://tex.z-dn.net/?f=7.5%3D7%2B%5Cfrac%7B1%7D%7B2%7D%3D7%5Cfrac%7B1%7D%7B2%7D)
The answer is A. 3° 87+90= 177+ 3= 180°
The projected population for 2015 should be 47,600. 32,800-18,000=14,800 so 14,800 times 3 is 47,600. Hope this helped :)
