The cross product is created.

Easiest way is probably cross-multiplying. a/b=c/d ad=bc There are other methods. Like (a+b)/b=(c+d)/d

Proportions: Our example: 4/x = 7/9First, find which fraction is missing a number/is replaced with a variable. In this case, it is the first one: 4/x. Next, cross multiply. You multiply the number shown in the variable fraction by the opposite number in the other fractions. So you would multiply 4x9, because one is a numerator and the other is a denominator. Once you get that number, divide it by the other number not used, which would be 7. 36 divided by 7 is 5.142857>. That means x=5.142857. Ratios: Ratios are any equations that compare numbers, like fractions or proportions. They can be written in proportion form: 4/5=7/8, or fraction form: 9/20.

No not all rectangles are similar because the proportions are different.

you use cross proportions. Ex: X 3 __________ = _______ 15 5 1. write the cross products 2. Multiply 5x=45 3. Think: What number times 5 equals 45? your answer is 9 OTHER: X=9

2.80 is 2.80: you do not need to ise proportions or anything to "find" it!

Yes, here's how you can show it, for the equivalent proportions a/b & (n*a)/(n*b): a na -=-- b nb Cross multiply: a*n*b ? b*n*a. Because multiplication is commutative, the question mark is an equal sign.

x/y= 2.8

The cross products of proportion are NEVER in cross formative. so the Mathematical... or ANY answer is... NEVER NEVER NEVER the answer is NEVER NEVER! if u have an account on moshi monsters please add me! my name is eatblueberries thank you!

The means-extreme property of proportions is the method that allows you to cross multiply an equation to find the answer. An example would be, if a/b = c/d then ad = bc.

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.
