To cross multiply with ratios, first set up the proportion as a fraction equation, such as ( \frac{a}{b} = \frac{c}{d} ). Then, multiply the numerator of the first fraction by the denominator of the second fraction (a × d) and the numerator of the second fraction by the denominator of the first fraction (b × c). This results in the equation ( a \times d = b \times c ), allowing you to solve for any unknown variable.

What is the difference between equal ratios and equivalent ratios?
To write equal ratios multiply both terms by the same number or divided both terms. For example, 2/ 9 is a ratio equal ratio will be 4/18. There is no difference between equal ratios and equivalent ratios.
How can you tell when two ratios form a proportion?
The simplest way is to check if their cross-products are the same. That is, if you have A/B and X/Y then if AY = BX the two ratios are equivalent.
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 can you determinate if two ratios are equivalent?
Multiply the antecedent of each ratio by the consequent of the other. If the products are equal, the ratios are equivalent.For example, given the two ratios A:B and C:D, if the product of A and D equals the product of B and C, then A:B::C:D (A is to B as C is to D).Two ratios a:b and c:d are equivalent if the crossproducts are the same.That is a/b = c/d if and only if a*d = b*c.
What the equilavent ratios of 5to 3?
Multiply both the numerator (top) and the denominator (bottom) of the ratio by any non-zero integer. You will have an equivalent ratio.
When you cross multiply two equal ratios the what are equal?
The products.
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.
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.
How can you determine if two ratios are equilvalent?
To determine if two ratios are equivalent, you can cross-multiply the terms. For example, if you have ratios ( a:b ) and ( c:d ), you check if ( a \times d = b \times c ). If the products are equal, the two ratios are equivalent. Alternatively, you can simplify both ratios to their lowest terms and see if they are the same.
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 10 percent of 40440400 dollars?
4044040 = 10% of 40440400. It is really easy to find the percentages because all you have to do is cross multiply and do ratios. For example x 10 ----= ----- 10 100 cross multiply 100x= 100 x=1 1= 10% of 10
what ratios can you use to determine whether the relationship is proportional?
look at the ratios and multiply
What does it mean if the cross products of two ratios are not equal?
The ratios are not equal.
When two or more ratios are equivalent?
When the cross-products of the two ratios are equal.
What value of x solves the following proportion?
To solve a proportion, you typically set the two ratios equal to each other and cross-multiply. For example, if you have ( \frac{a}{b} = \frac{c}{x} ), you would cross-multiply to get ( a \cdot x = b \cdot c ), and then solve for ( x ) by rearranging the equation to ( x = \frac{b \cdot c}{a} ). Please provide the specific values or ratios for a more precise answer.
When you multiply fraction do you cross multiply?
No you only cross multiply when your working with percent
Is 8 to 9 proportional to 18 to 16?
Oh, what a lovely question! To find out if two ratios are proportional, we can cross multiply and see if the results are equal. So, for 8 to 9 and 18 to 16, when we cross multiply (8 x 16 and 9 x 18), we see that they are not equal. That means these ratios are not proportional, but it's all part of the happy little journey of learning!
