What is the proportion of 2 over 5 equals 7 over x?
Easy. Cross multiply to get 2x = 35. Then, divide by two to get 35/2.
How much is 20 percent of 35?
You can solve this 2 ways (probably more but I only really know 2). Proportion and Multiplication.(20/100)=(x/35)20*35=700700/100=7OR(.2 is equivalent to 20%).2*35=7.0
Solve the proportion 2 over 7 equals x over 28?
2/7=x/28 56=7x 8=x
Solve the proportion 2 over 7 equals x over 14?
2/7=x/14 28=7x 4=x
Solve the proportion 2 over 6 equals x over 30?
2/6=x/30 60=6x 10=x
Solve the proportion 2 over 9 equals x over 72?
2/9=x/72 144=9x 16=x
How do you solve proportions using cross products?
say it is 1 over 2 is equal to x over 4 you multiply 4 and 1 then 2 and x and you get 4=2x. Solve for x = 2. So the equivalent proportion is 2/4.
Solve the proportion 1 over 6 equals x over 12?
1/6=x/12 12=6x 2=x
Solve the proportion 1 over 9 equals x over 18?
1/9=x/18 18=9x 2=x
Random sampling of 100 women over the age of 35 showed 8 of the women were married 2 or more times based on the study how many women in a group of 5000 women over age of 35 would be married 2 or more?
Assuming the proportion of women over 35 who are married 2 or more times is consistent, we can calculate the proportion found in the sample (8/100 = 0.08). Applying this proportion to the larger group of 5000 women would mean approximately 400 women over the age of 35 in a group of 5000 would be married 2 or more times.
Solve equation 32x-1 equals 5-3x-2?
x equals 4 over 35
How To Solve A Proportion?
To solve a proportion, you cross multiply. For example, if this was the proportion: 2/4 = 3/x, you would multiply 2 with x and 4 with 3. The products will be used in your next equation. In this case, your next equation is 2x = 12. Now you want to isolate x, so divide by two for both sides. Your answer will be x = 6.
