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
What is the product of numerators and opposite denominators in a proportion called?
The answer is cross products.
What is an equation that sets two fractions equal to each other called?
An equation that sets two fractions equal to each other is called a proportion. In a proportion, the cross products of the fractions are equal. For example, if you have the proportion ( \frac{a}{b} = \frac{c}{d} ), then ( ad = bc ). Proportions are commonly used in solving problems involving ratios and rates.
If cross products are equal the ratios are equal?
Yes, they are.
What does it mean if the cross products of two ratios are not equal?
The ratios are not 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 is true about the cross products of a proportion?
They're equal
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.
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
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
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!
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 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.
What is the meaning of equal proportion?
when you cross multiply you get the same number for each side its an equal proportion
What happens to the cross products when the terms of a proportion are cross multiplied?
The cross product is created.
What is the product of numerators and opposite denominators in a proportion called?
The answer is cross products.
What are some characteristics of proportions?
Proportions show a relationship between two equal ratios. They maintain equality when both sides are multiplied or divided by the same number. In a proportion, the cross-products are always equal.
