This fraction calculator performs basic and advanced fraction operations, expressions with fractions combined with integers, decimals, and mixed numbers. It also shows detailed step-by-step information about the fraction calculation procedure. The calculator helps in finding value from multiple fractions operations. Solve problems with two, three, or more fractions and numbers in one expression.
1 3/4 * 3 = 21/ = 5 1/ = 5.25Spelled result in words is twenty-one quarters (or five and one quarter).
How do we solve fractions step by step?
- Conversion a mixed number 1 3/ to a improper fraction: 1 3/4 = 1 3/ = 1 · 4 + 3/ = 4 + 3/ = 7/
To find a new numerator:
a) Multiply the whole number 1 by the denominator 4. Whole number 1 equally 1 * 4/ = 4/
b) Add the answer from the previous step 4 to the numerator 3. New numerator is 4 + 3 = 7
c) Write a previous answer (new numerator 7) over the denominator 4.
One and three quarters is seven quarters.
- Multiple: 7/ * 3 = 7 · 3/ = 21/
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(21, 4) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seven quarters multiplied by three is twenty-one quarters.
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. If you use mixed numbers, leave a space between the whole and fraction parts.
Mixed numerals (mixed numbers or fractions) keep one space between the integer and
fraction and use a forward slash to input fractions i.e., 1 2/3 . An example of a negative mixed fraction: -5 1/2.
Because slash is both sign for fraction line and division, use a colon (:) as the operator of division fractions i.e., 1/2 : 1/3.
Decimals (decimal numbers) enter with a decimal point . and they are automatically converted to fractions - i.e. 1.45.
