must play an important part to be able to make a proportional recipe. To double the quantities of items with a whole number amount is easy‚ but what about those fractions? Let’s focus on the 1 1/3 cups uncooked spiral pasta. To double that‚ we multiply by 2. 1 1/3 x 2 Change each fractional amount to an improper fraction. = 4/3 x 2/1 Multiply numerator times numerator and denominator times denominator to get: = 8/3 Now simplify. = 2 2/3 cups of pasta References Ratatouille Pasta

convert an expression to one involving only a single function‚ provided no radicals are introduced. Consider the possibilities of applying algebraic processes (multiplying‚ factoring‚ combining fractions into a single fraction‚ etc.). To obtain a particular factor in the numerator or denominator of a fraction‚ you may multiply the numerator and denominator by a desired factor.

Solving Proportions MATT222 Intermediate Algebra A comparison of two numbers is referred to as a ratio‚ similar to fractions that can be reduced to lowest terms and then converted into a ratio of integers. Ratios allow one to compare sizes of two quantities and unit measurements. Any statement expressing the equality of two ratios is known as a proportion‚ which is used in numerous formulas in today’s real world settings and applications. Using proportions is an effective
