Divide 7 15 by 3 5
Fraction calculator
This calculator divides fractions. The first step makes the reciprocal value of the second fraction – exchange numerator and denominator of 2nd fraction. Then multiply both numerators and place the result over the product of both denominators. Then simplify the result to the lowest terms or a mixed number.
The result:
3/5÷2/3 =
9
/
10
=
0.9
Spelled result in words is nine tenths.

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first substep is to find the reciprocal (reverse the numerator and denominator, reciprocal of
2
/
3
is
3
/
2
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words – three fifths divided by two thirds is nine tenths.
Rules for expressions with fractions:
Fractions
– use a forward slash to divide the numerator by the denominator, i.e., for fivehundredths, 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.

The calculator follows wellknown 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.
