<span>The ratio of similarity is simply the number you multiply by to scale from one similar object to another. Since you've been told the smallest object has an edge length of 6 inches, just multiply each of the ratios by 6 to get the length of their edge. So
1.25: 1.25 * 6 inches = 7.5 inches
4/3: 4/3 * 6 inches = 24/3 inches = 8 inches
1.5: 1.5 * 6 inches = 9 inches
7/4: 7/4 * 6 inches = 42/4 inches = 21/2 inches = 10.5 inches
2: 2 * 6 inches = 12 inches</span>
Hello. Good?
Formula for calculating two overlapping sets:
A + B - both + not (A or B) = Total
20 (french) + 20 (german) - 10(both) + Not = 50
40 - 10 + not = 50
30 + not = 50
not = 50 - 30
not = 20
Answer: 20 students do not speak french or german.
