What is an equation that shows that two ratios are equivalent

8:24 is equal to 1:3 I hope this helps

I'm not sure about an "official" equation, but the way I would do it when I was younger is by "cross multiplication". You write the two ratios as a fraction, then you multiply the "numbers" across. writing the product on the top side of the ratio. Bottom left times top right and bottom right times top left. This can also be used to see which ratio is larger, if the products don't match, then the ratio with the larger outcome is bigger. In the attached pdf you can see what I'm talking about. t=The t=ratios used are "27:100  24,300:90,000".

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
