Question

How many 2/5 s are in 1 1/2?

Answer 1

$3\frac{3}{4}$ number of $\frac{2}{5}$s in $1\frac{1}{2}$.

Solution:

To find how many $\frac{2}{5}$ s are in $1\frac{1}{2}$.

Let us first convert the mixed fraction into improper fraction.

$1\frac{1}{2}=\frac{(1\times2)+1}{2}$

    $=\frac{2+1}{2}$

$1\frac{1}{2}=\frac{3}{2}$

Now, divide $1\frac{1}{2}$ by $\frac{2}{5}$.

$1\frac{1}{2}\div\frac{2}{5} =\frac{3}{2}\div\frac{2}{5}$

Using fractional rule, $\frac{a}{b}\div\frac{c}{d}=\frac{a}{b}\times\frac{d}{c}$

            $=\frac{3}{2}\times \frac{5}{2}$

            $=\frac{3\times 5}{2\times 2}$

            $=\frac{15}{4}$

Again, convert into a mixed fraction,

           $=3\frac{3}{4}$

$1\frac{1}{2}\div\frac{2}{5} =3\frac{3}{4}$

There are $3\frac{3}{4}$ number of $\frac{2}{5}$s in $1\frac{1}{2}$.
