To determine if two ratios form a proportion, you can use cross-multiplication. If the cross-products of the ratios are equal, the ratios are proportional. For example, for the ratios ( \frac{a}{b} ) and ( \frac{c}{d} ), if ( a \times d = b \times c ), then the two ratios form a proportion. Additionally, you can also compare the decimal values of the ratios; if they are equal, they are proportional.
look at the ratios and multiply
To determine if the ratios 316 and 1264 form a proportion, we can compare them by setting up the fraction 316/1264. If the two ratios are equivalent, their cross products should be equal. However, simplifying 316/1264 gives us 1/4, meaning they do not form a proportion since they are not equivalent. Therefore, the ratios do not form a proportion.
When two ratios form a proportion, the ratios are equal
To determine if the ratios ( \frac{2}{1} ) and ( \frac{20}{10} ) form a proportion, we can compare their cross products. The cross products are ( 2 \times 10 = 20 ) and ( 1 \times 20 = 20 ). Since both cross products are equal, the ratios do form a proportion.
An equation that states that two ratios are equal is a proportion.
... a proportion.... a proportion.... a proportion.... a proportion.
set up a proportion and see if both sides simplify to the same answer. If the 2 ratios represent a constant ratio they will simplify into fractions
