What is the ratio of rise to run between the points -2 8 and 4 -3?
Rise = 8 - (-3) = 11 Run = -2 - 4 = -6 So ratio = -11/6
What is the ratio of 11 quarts to 3 gallons?
11 quarts : 3 gallons = 11 quarts : 3*4 = 12 quarts = 11:12
If there are 77 students in the student council and the ratio of girls to boys is 7 to 4. How many girls are in the student council What is the ratio of girls to students?
With a ratio of 7:4 there are 7+4 = 11 parts - 7 parts are girls, 4 parts are boys. 77 students / 11 parts = 7 students/part Girls are 7 parts → girls = 7 students/part × 7 parts = 49 students For the ratio of girls : students, you can either use the figure just found: 49 : 77 = 7 : 11, or just go back to the original ratio: 11 parts are students, 7 of those parts are girls → ratio girls : students = 7 : 11
How can you divide 45 into three parts in the ratio 2 4 5?
Well you need to find out how many parts are needed: 2+4+5 = 11 Therefore each part of the ratio is (45/11)x2 : (45/11)x4 : (45/11)x5 Do the calculator work yourself
What is the equivalent ratio of 10 and 11?
Multiply both numbers of the ratio, 10/11, by any non-zero number. You will have an equivalent ratio.
How to convert 2 4 5 to a ratio?
2 : 4 : 5 is equivalent to 2/11 : 4/11 : 5/11.
What is the ratio of 44 quarts to 11 quarts?
4 to 1
What is the ratio of rise to run between the points -2 8 and 4 -3?
Rise = 8 - (-3) = 11 Run = -2 - 4 = -6 So ratio = -11/6
How do you find the scale factor if they give you the perimeter ratio?
Let's get at the idea by working backward. Suppose we know the scale factor; what will the ratio of perimeters be? For instance, suppose we have two triangles; one has sides of 3, 4, and 5 inches; the other has sides of 33, 44, and 55 inches. The scalefactor is 11: you multiply each side length of the first triangle to get the corresponding side length of the second triangle. Now look at the perimeters. The perimeter of the first triangle is 3+4+5 = 12 inches. The perimeter of the second triangle is 33+44+55 = 132 inches. The ratio of perimeters is 132/12 = 11. Do you notice that it's the same as the scale factor? This will always be true! Here is why. We can write the sides of the second triangle as 3*11, 4*11, and 5*11. Then the perimeter is 3*11 + 4*11 + 5*11 = (3 + 4 + 5)*11 using the distributive property. To find the ratio of perimeters, divide this by the perimeter of the first triangle: (3+4+5)*11 ---------- = 11 3+4+5 Let's continue and think about the ratio of areas. The triangles I chose happen to be right triangles (do you know how to show this?) so the area is half the product of the two shorter sides. Thus the area of the first triangle is (3*4)/2 = 6 square inches. The area of the second triangle is (33*44)/6 = 726 square inches. The ratio of areas is 726/6 = 121. This ratio happens to be 11 squared. It will always be true that the ratio of areas is the square of the scale factor. Again, we can see why this is true. Writing the sides of the second triangle as 3*11 and 4*11, the area is 3*11 * 4*11 = (3*4)*(11*11) Divide this by the area of the first triangle to find the ratio of areas: (3*4)*(11*11) ------------- = 11*11 = 11^2 3*4 Do you see how it works now? What is the answer to your problem?
How do you find the ratio of a triangle shortest side to longest?
11 1/2 to 4 1/4
What is the ratio of 11 quarts to 3 gallons?
11 quarts : 3 gallons = 11 quarts : 3*4 = 12 quarts = 11:12
If there are 77 students in the student council and the ratio of girls to boys is 7 to 4. How many girls are in the student council What is the ratio of girls to students?
With a ratio of 7:4 there are 7+4 = 11 parts - 7 parts are girls, 4 parts are boys. 77 students / 11 parts = 7 students/part Girls are 7 parts → girls = 7 students/part × 7 parts = 49 students For the ratio of girls : students, you can either use the figure just found: 49 : 77 = 7 : 11, or just go back to the original ratio: 11 parts are students, 7 of those parts are girls → ratio girls : students = 7 : 11
What is the ratio of 11 to 132?
To find the ratio of 11 to 132, you simply divide 11 by 132: Ratio= 11/132 Now, let's simplify this ratio: Ratio = 11/132 = 1/12
