How can you tell if a proportion is false?
Multiply the cross products, and see if they are equal. If they are equal, the proportion is true. If they are unequal, the proportion is false.
Can a proportion be equal if the cross products are not equal?
No. A cross product is just a way of simplifying a proportion. If the cross product aren't equal, it follows logically that the proportion isn't equal.
The cross products of a proportion are equal Always Sometimes or Never?
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!
What is a cross product and give an example?
It's part of a proportion. The cross products in a proportion are equal. example: 3/4 = 15/20 4x15 = 60 3x20 = 60
What are two ways you can tell a ratio form a proportion?
The simplified forms of the two ratios are the same.The cross products are the same: a/b = c/d if ad = bc
How can you tell if a proportion is false?
Multiply the cross products, and see if they are equal. If they are equal, the proportion is true. If they are unequal, the proportion is false.
What is a true proportion?
A true proportion is when two ratios are equal to one another. To prove this, you need to find the cross products of the ratios and see if they are equal. An example of a true proportion are the ratios 1/2 and 5/10, if you take the cross product the result is 2 x 5 = 1 x 10, which are equal.
Can a proportion be equal if the cross products are not equal?
No. A cross product is just a way of simplifying a proportion. If the cross product aren't equal, it follows logically that the proportion isn't equal.
What happens to the cross products when the terms of a proportion are cross multiplied?
The cross product is created.
How can you tell if a proportion is true?
If you cross-multiply and you obtain an equality, then the proportion is true. Example: 2/3 = 20/30 ? cross-multiply; 2 x 30 = 3 x 20 ? 60 = 60 Since we have an equality, the proportion is true.
What is the product of numerators and opposite denominators in a proportion called?
The answer is cross products.
The cross products of a proportion are equal Always Sometimes or Never?
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!

Determine whether the ratios 9 15 and 6 10 form a proportion Justify your answer?
The fractions are proportional and their cross products are equal
How are cross products useful in solving a proporton?
The cross products are equal. If there is a variable you can make that variable so it will make the proportion equal. 1/2=x/14 1x14=2x So x=7
What is the number that is being compared to the whole quantity as a percentage proportion?
I think it is cross products I could be wrong but thats what im leaning to(:
A statement that 2 ratios are equal?
A statement that two ratios are equal is called a proportion in math. An example of a proportion is 1/2 equals 2/4. In this proportion, if you cross multiply, you find that 4 x1 is equal to 2 x 2, which is a true statement or proportion.
