First inherit 1/2, second 1/4, third 1/5 of property. How many meters of textile remained in the package? Is Peter’s calculation correct? Using words (math vocabulary) and numbers explain why he is correct or incorrect. and they are automatically converted to fractions - i.e. An example of a negative mixed fraction: -5 1/2.īecause slash is both signs for fraction line and division, use a colon (:) as the operator of division fractions i.e., 1/2 : 1/3.ĭecimals (decimal numbers) enter with a decimal point. Mixed numerals (mixed numbers or fractions) keep one space between the integer andįraction and use a forward slash to input fractions i.e., 1 2/3. If you use mixed numbers, leave a space between the whole and fraction parts. Rules for expressions with fractions: Fractions - use a forward slash to divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100. In other words - one hundred thirty-one eighths minus seventy-seven eighths is twenty-seven quarters. In the following intermediate step, cancel by a common factor of 2 gives 27 / 4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 8 = 64. The common denominator you can calculate as the least common multiple of both denominators - LCM(8, 8) = 8. Subtract: 131 / 8 - 77 / 8 = 131 - 77 / 8 = 54 / 8 = 2 įor adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator.Nine and five eighths is seventy-seven eighths

New numerator is 72 + 5 = 77Ĭ) Write a previous answer (new numerator 77) over the denominator 8. Whole number 9 equally 9 * 8 / 8 = 72 / 8ī) Add the answer from previous step 72 to the numerator 5. Conversion a mixed number 9 5 / 8 to a improper fraction: 9 5/8 = 9 5 / 8 = 9 Ī) Multiply the whole number 9 by the denominator 8.Sixteen and three eighths is one hundred thirty-one eighths New numerator is 128 + 3 = 131Ĭ) Write a previous answer (new numerator 131) over the denominator 8.

Whole number 16 equally 16 * 8 / 8 = 128 / 8ī) Add the answer from previous step 128 to the numerator 3.
