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.
Do the ratios 2 1 and 20 10 form a proportion?
To determine if the ratios ( \frac{2}{1} ) and ( \frac{20}{10} ) form a proportion, we can compare their cross products. The cross products are ( 2 \times 10 = 20 ) and ( 1 \times 20 = 20 ). Since both cross products are equal, the ratios do form a proportion.
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
How can you tell if a 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.

Which one of the following statements expresses a true proportion 14628 2332 42762 351220?
To determine which statement expresses a true proportion among the numbers 14628, 2332, 42762, and 351220, we need to compare the ratios of these numbers. A true proportion means that the cross products of the ratios are equal. Without additional context or specific pairs to compare, it's not possible to identify a true proportion directly from these numbers. Please provide more details or specific pairs for comparison.
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
