When two or more ratios are equivalent?
When the cross-products of the two ratios are equal.
How do you figure out if two fractions are equal or not?
cross multiply
Are two ratios always equal to each other?
No but the equal ratios are called Equivalent Ratios.
How do you determine if more than two ratios are equivalent or not?
Cross-multiply them in pairs. The ratios are the same if and only if the answers are the same. Thus a/b = c/d iff a*d = b*c.
What is the equal ratio for 1 to 7?
An equal ratio would be 2:154, for further ratios just multiply both parts by two because the ratio continues to function.
How do you know if ratios are equivalent?
Cross-multiply them. Given A/B and C/D, if AD = BC then the two ratios are equal.
What does it mean if the cross products of two ratios are not equal?
The ratios are not equal.
When do you cross multiply in dividing fractions?
To divide fractions, turn the second one over - that is, swap its numerator and denominator - and multiply. Nothing else is necessary. You cross multiply when you have a proportion, that is when you have two ratios that are equal.
When two or more ratios are equivalent?
When the cross-products of the two ratios are equal.
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.
How do you figure out if two fractions are equal or not?
cross multiply
When are 2 ratios equal?
The two ratios are said to be equal when even if we multiply both terms by the same number or divided both terms , the equivalent fraction or simplest fraction is the same.
How do you describe a proportion?
A proportion is a statement that two ratios are equal. It is often written as a fraction with an equal sign between the numerators and denominators of the ratios. Proportions are used to compare the relationship between different quantities.
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.
Are two ratios always equal to each other?
No but the equal ratios are called Equivalent Ratios.
How do you determine if more than two ratios are equivalent or not?
Cross-multiply them in pairs. The ratios are the same if and only if the answers are the same. Thus a/b = c/d iff a*d = b*c.
What it means when two ratios are equal?
They are equivalent ratios
