When subtracting two fractions with the same denominator, we
subtract their numerators, and
keep the denominator the same.
For example, let's compute the following difference:
We subtract the numerators and keep the denominators the same. Therefore,
We can use a fraction model to confirm this result:
Find the value of
To subtract two fractions with like denominators, we subtract the numerators and keep the denominators the same. Therefore,
$\dfrac 5 6 - \dfrac 4 6 = $
|
a
|
$\dfrac 1 6$ |
|
b
|
$\dfrac 1 3$ |
|
c
|
$\dfrac 2 3$ |
|
d
|
$\dfrac 1 {12}$ |
|
e
|
$\dfrac 5 6$ |
$\dfrac 4 5 - \dfrac 2 5 = $
|
a
|
$\dfrac{2}{25}$ |
|
b
|
$\dfrac{8}{25}$ |
|
c
|
$\dfrac{8}{5}$ |
|
d
|
$\dfrac{2}{5}$ |
|
e
|
$\dfrac{2}{0}$ |
What is the value of
To subtract two fractions with like denominators, we subtract the numerators and keep the denominators the same. Therefore,
We can simplify this fraction by dividing the numerator and the denominator by
Therefore, we conclude that
$\dfrac{3}{4} - \dfrac{1}{4} =$
|
a
|
$\dfrac 3 4$ |
|
b
|
$\dfrac 5 8$ |
|
c
|
$\dfrac 1 4$ |
|
d
|
$\dfrac 1 2$ |
|
e
|
$\dfrac 3 8$ |
$\dfrac{8}{9} - \dfrac{2}{9} =$
|
a
|
$\dfrac 2 3$ |
|
b
|
$\dfrac 5 9$ |
|
c
|
$\dfrac 1 3$ |
|
d
|
$\dfrac 1 9$ |
|
e
|
$\dfrac 4 9$ |
Find the value of
To subtract two fractions with like denominators, we subtract the numerators and keep the denominators the same. Therefore,
We can simplify this fraction by dividing the numerator and the denominator by
Since we can write the answer as a mixed number:
Therefore, we conclude that
$\dfrac{12}{5} - \dfrac{3}{5} = $
|
a
|
$1\, \dfrac{3}{5}$ |
|
b
|
$2\, \dfrac{1}{5}$ |
|
c
|
$1\, \dfrac{2}{5}$ |
|
d
|
$2\, \dfrac{3}{5}$ |
|
e
|
$1\, \dfrac{4}{5}$ |
$\dfrac{19}{6} - \dfrac{5}{6} =$
|
a
|
$1 \, \dfrac{5}{6}$ |
|
b
|
$2 \, \dfrac{1}{6}$ |
|
c
|
$1 \, \dfrac{2}{3}$ |
|
d
|
$2 \, \dfrac{1}{3}$ |
|
e
|
$2 \, \dfrac{2}{3}$ |
