Question

by what number should 1 ½ be divided to get ⅔?​

Answer 1

${ \mathfrak { \huge{ \red{a}{ \huge{ \green{n}{ \huge{\blue{s}{ \huge{\pink{w}{ \huge{\orange{e}{ \huge \red{r}}}}}}}}}}}}} \\ \\ { \huge{ \red{ \ \: hope \: this \: helps \: u}}} \\ \\ { \huge{ \orange{ \ brainlist \: pls}}}$

Answer 2

Assume that n is the required number.

Then,

       $\rm 1\dfrac{1}{2} \div n = \dfrac{2}{3}\\\\\\\\ \dfrac{3}{2}\div n= \dfrac{2}{3}\\\\\\ \dfrac{3}{2} \times \dfrac{1}{n}=\dfrac{2}{3}\\ \\ \\ \dfrac{\dfrac{3}{2}\times \dfrac{1}{n}}{\dfrac{3}{2}}=\dfrac{\dfrac{2}{3}}{\dfrac{3}{2}}\\ \\ \\ \dfrac{1}{n}=\dfrac{4}{9}\\ \\ \\\therefore n = \frac{9}{4}$

Hence,

• 1 ½  should be divided by 9/4 to get 2/3
