Answer: 198 left handed students
Step-by-step explanation:
You have to divide the 1650 by 25 and that equals 66 then multiply by 3 and that equals 198
Step 1: Reduce (simplify) entered fractions to lowest terms, if the case:
Fraction: 9 / 10 it's already reduced to lowest terms
Fraction: 11 / 12 it's already reduced to lowest terms
Step 2: Calculate LCM (lowest common multiple) of the reduced fractions' denominators, it will be the common denominator of the compared fractions:
Denominator 10, factored = 2 * 5
Denominator 12, factored = 22 * 3
LCM (10, 12) = 22 * 3 * 5 = 60
Step 3: Calculate each fraction's expanding number (LCM divided by each fraction's denominator):
For fraction: 9 / 10 is 60 : 10 = (22 * 3 * 5) : 10 = 6
For fraction: 11 / 12 is 60 : 12 = (22 * 3 * 5) : 12 = 5
Step 4: Expand fractions to bring them to the common denominator (LCM):
9 / 10 = (6 * 9) / (6 * 10) = 54 / 60
11 / 12 = (5 * 11) / (5 * 12) = 55 / 60
Answer: 210 advanced tickets were sold. 130 same day tickets were sold.
Step-by-step explanation:
x= advanced tickets y=same day tickets
2x+3y=810 this equation represents the money
x+y=340 this equation represents the total number of tickets
x+y=340
<u>-x -x</u>
y=-340-x 2x+3(340-x)=810 210+y=340
2x+1020-3x=810 <u> -210 -210 </u>
-x+1020=810 y=130
<u> -1020 -1020</u>
<u>-x</u>=-<u>210</u>
-1 -1
x=210
Answer:
150.9
Step-by-step explanation:
2/3x=100.6
x=100.6/(2/3)
x=100.6(3/2)
x=150.9
