What is 4 5-2 8

It can sometimes be difficult to add fractions, such as 4/5 plus 2/8. But it's no problem! We have displayed the answer below:

4/5 + 2/8 = 1 1/20

How did we solve the problem above? When we add two fractions, such as 4/5 + 2/8, we make sure that the two denominators are the same and then we simply add the numerators.

In cases where the denominators are not the same, we find the lowest common denominator and adjust the fractions to keep them intact.

We also simplify the answers to fraction problems whenever possible.

1. Conversion a mixed number 4 5/8 to a improper fraction: 4 5/8 = 4 5/8 = 4 · 8 + 5/8 = 32 + 5/8 = 37/8

   To find a new numerator:
   a) Multiply the whole number 4 by the denominator 8. Whole number 4 equally 4 * 8/8 = 32/8
   b) Add the answer from previous step 32 to the numerator 5. New numerator is 32 + 5 = 37
   c) Write a previous answer (new numerator 37) over the denominator 8.

   Four and five eighths is thirty-seven eighths

2. Conversion a mixed number 2 3/4 to a improper fraction: 2 3/4 = 2 3/4 = 2 · 4 + 3/4 = 8 + 3/4 = 11/4

   To find a new numerator:
   a) Multiply the whole number 2 by the denominator 4. Whole number 2 equally 2 * 4/4 = 8/4
   b) Add the answer from previous step 8 to the numerator 3. New numerator is 8 + 3 = 11
   c) Write a previous answer (new numerator 11) over the denominator 4.

   Two and three quarters is eleven quarters

3. Add: 37/8 + 11/4 = 37/8 + 11 · 2/4 · 2 = 37/8 + 22/8 = 37 + 22/8 = 59/8
   For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(8, 4) = 8. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 4 = 32. In the following intermediate step, it cannot further simplify the fraction result by canceling.
   In other words - thirty-seven eighths plus eleven quarters is fifty-nine eighths.

Input fractions

This 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.

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 signs 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.

Math Symbols

The calculator follows well-known rules for the order of operations. The most common mnemonics for remembering this order of operations are:
PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction
BODMAS - Brackets, Of or Order, Division, Multiplication, Addition, Subtraction.
GEMDAS - Grouping Symbols - brackets (){}, Exponents, Multiplication, Division, Addition, Subtraction.
MDAS - Multiplication and Division have the same precedence over Addition and Subtraction. The MDAS rule is the order of operations part of the PEMDAS rule.
Be careful; always do multiplication and division before addition and subtraction. Some operators (+ and -) and (* and /) has the same priority and then must evaluate from left to right.
