What value of x makes each pair of ratios equivalent?
The answer will depend on what the ratios are. But since you have not bothered to provide that information, I cannot provide a sensible answer.
How do you do this There are 123 chocolates in a box They are either plain milk or white The ratio of plain to milk is 2 to 3 The ratio of milk to white is 7 to 2 Find the number of plain chocolates?
As "milk" appears in both ratios you need to create equivalent ratios with the same value of "milk" in each; then you can combine the two ratios in to one ratio for all three and use that ratio to solve the problem.Equivalent ratios are like equivalent factions: whatever you multiply/divide one side of the ratio by, you must multiply/divide the other side by the same amount and you will have an equivalent ratio - this is how ratios are simplified.The first ratio plain : milk = 2 : 3The second ratio milk : white = 7 : 2To avoid fractions, use the lcm of the value of the "milk" in both ratios: ie the lcm(3, 7) = 21 as the value of "milk" in the equivalent ratios - divide the lcm by the current value to find what number you need to multiply the ratio by:The first ratio can be multiplied by 21 ÷ 3 = 7 to give:plain : milk = 2 : 3 = 2×7 : 3×7 = 14 : 21The second ratio can be multiplied by 21 ÷ 7 = 3 to give:milk : white = 7 : 2 = 7×3 : 2×3 = 21 : 6The two ratios can now be combined in a single ratio with three terms as the "milk" is 21 in each case, forming:plain : milk : white = 14 : 21 : 6From this we can find how many of each type of chocolate there are, and in particular how many plain ones there are:There are 14 + 21 + 6 = 41 parts→ each part is worth 123 chocs ÷ 41 parts = 3 chocs per part→ There are 14 parts × 3 chocs per part plain = 42 plain chocolates-------------------------------------------------------------------To check we can also work out the quantity of the other two types of chocolates:& There are 21 parts × 3 chocs per part milk = 63 milk& There are 6 parts × 3 chocs per part white = 18 whiteThis gives a total box of 42 plain + 63 milk + 18 white = 123 chocolatesAnd recalculate the ratios, simplifying them:Ratio of plain : milk = 42 : 63 = 2×21 : 3×32 = 2 : 3Ratio of milk : white = 63 : 18 = 7×9 : 2×9 = 7 : 2
Can you create an equivalent ratio by adding the same number to each quantity in the ratio?
No. It is necessary to multiply.
How can you use a table to decide if a relationship is proportional?
If the ratio between each pair of values is the same then the relationship is proportional. If even one of the ratios is different then it is not proportional.
How do you convert ratios to ppm?
If you have a ratio (A/B) ... (you know the numbers 'A' and 'B') ... write the equationx / 1,000,000 = A/Band solve it for 'x'. 'x' is the ppm. Here's what the solution looks like:Multiply each side by 1 million:x = 1,000,000 A / Band there you have it.
Write five equivalent ratios for each ratio?
45:24
What is the ratio of 531054006300?
A ratio is 531054006300:1. To obtain equivalent ratios simply multiply each of these numbers by any non-zero number.
What is a similarity ratio?
similarity ratios are ratios in which both the ratios are equal to each other
In a table if the ratios weren't equivalent would it still be direct variation?
No; each ratio has to be the same for a direct variation.
Write tree equivalent ratios for each ratio 18 6?
3:1, 6:2, 9:3
How do you do equivalent ratios?
Multiply each part of the ratio by the same number.
Are two ratios always equal to each other?
No but the equal ratios are called Equivalent Ratios.
What is the comparison of a rational number and a ratio?
I have no idea what "compersion" means or what you are trying to say. A rational number is so called because it can be expressed as ratio of two integers. Each rational number is a ratio and each ratio is a rational number. However, the relationship is not one of equivalence: each rational number can be represented by infinitely many equivalent ratios.
Are decimals related to ratios?
Yes,decimal are related to ratios in mathematics. When a ratio is solved or two numbers are not divisible by each other then the result of the division of the ratio is decimal number only.
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 are two ratios that are equal to each other called?
Equivalent
How to get the equivalent ratios of 60:12?
The calculator will simplify the ratio A : B if possible. Otherwise the calculator finds an equivalent ratio by multiplying each of A and B by 2 to create values for C and D. Compare Ratios and Solve for the Missing Value: Enter A, B and C to find D.
