They would need 3 steaks and 6 sausages. This is the result, if you divide all numbers by 5. Now you have only to divide all numbers by 36. The definition of a ratio differs from that of a fraction but all rules for manipulating fractions apply to ratios. If a ratio of two values is known, then percent that one of the values is of the total can be determined by adding the parts to get the whole, placing the one value over the whole, an multiplying by 100.
Variation describes how one quantity varies or changes as another quantity varies or changes.
If as one number increases then decreases, another number increases then decreases simultaneously, the numbers are in direct variation or direct proportion to each other. The k represents some constant number, and x and y represent numbers that vary directly. As x increases, y increases. As y increases, x increases. If as one number increases then decreases, another number decreases then increases simultaneously, the numbers are in indirect variation and are said to be inversely proprotional .
