Answer:
2,200 students
Step-by-step explanation:
To find the number of students, create a proportion which is two equal ratios. Since the middle school and the high school are proportional then they have equal ratios.
Solve for x by cross multiplying by multiplying the numerator and denominator of each fraction.
900(110) = 45(x)
99,000=45x
2,200 = x
218.7 / 6.75 = 32.4 you divide the area by the base
Answer:
a) 416/100 = 4.16
b) 46/10 = 4.6
c) 406/100 = 4.06
Step-by-step explanation:
a) 4 + 16/100 = 4(100/100) +16/100 = (400 +16)/100 = 416/100 = 104/25
4 + 16/100 = 4 +0.16 = 4.16
__
b) 4 + 6/10 = 4(10/10) +6/10 = (40 +6)/10 = 46/10 = 23/5
4 +6/10 = 4 +0.6 = 4.6
__
c) 4 +6/100 = 4(100/100) +6/100 = (400 +6)/100 = 406/100 = 203/50
4 +6/100 = 4 +0.06 = 4.06

<em>Comment on place value</em>
Since you're familiar with the decimal place-value number system, you know that digits in the ones place are multiplied by 1; digits in the tenths place are multiplied by 1/10 or 0.1; and digits in the hundredths place are multiplied by 1/100 or 0.01. These same multipliers can be represented as powers of 10: 10^0, 10^-1, 10^-2, respectively.
