Using Ratios and Proportions HelpingWithMath.com
Calculate problems involving ratios by multiplying both parts by the same number to scale the ratio up or down. To turn ratios into real-world values, find one “part” in the ratio by adding its two sides together and dividing the total real-world amount by this number. Multiply your value for one part by both sides of the ratio to find the ratio as a real world amount.... For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2. Do you see that these ratios both represent the same comparison? Some other equal ratios are listed below. To find out if two ratios are equal, you can divide the first number by the second for each ratio. If the quotients are equal, then the ratios are equal. Is the ratio 3:12 equal to
