How to write a ratio as a fraction?
The order of the quantities in a ratio is important. In order to write a ratio as a fraction, use the following steps. Example: Write the ratio 2 to 3 as a fraction. The order of the numbers is very important. The ratio 2 to 3 is . The fraction is incorrect. Ratios can be simplified by writing them in lowest terms.
What is a fraction whose denominator is 2?
From this point of view, fractions are the “numbers” we must add to whole numbers in order to secure an affirmative answer to this question. Indeed, we can get all fractions whose denominators are 2 by letting B = 2 and letting A be successively 1, 2, 3, . . . . Because then the requisite C’s are exactly 1 2, 2, 3 2, 2 . . .
Is a ratio a division of two numbers?
As the definitions given above of ratio and rate make it abundantly ob- vious, a rate or a ratio is just a division of two numbers, and because we have made the extra effort to explain what division means, these definitions at least have the merit of being correct.
Can a ratio table be used to simplify fractions?
: 3 ? 1 ? 10 Now show students that a ratio table can also be used to simplify fractions. List all the answers you got for 3⁄10 + /4 (55⁄100, 33⁄60, 1/20, 22⁄40), and ask students to compare them.

and ratio — are found in most elementary mathematics pro-grams. Part-wholeThe part-whole interpretation of a fraction such as 2 3 indicates that a whole has been partitioned into three equal parts and two of those parts are being considered. Quotient The fraction 2 3 may also be considered as a quo-tient, 2 ÷ 3.
