Question

Write the multiplicative inverse $:$

$2\frac{1}{4}$

Answer 1

Step 1 First convert mixed number into improper fraction

$\Rightarrow$$2\frac{1}{4}$ $=\frac{2\times 4+1}{4}=\frac{9}{4}$

Step 2 To get the multiplicative inverse of a fractional number , write the numerator and denominator of the fraction as the denominator and numerator respectively

$\Rightarrow \frac{9}{4}$ here numerator is $9$ and denominator is $4$

Now denominator is $9$ and numerator is $4$

Therefore, the multiplicative inverse of $2\frac{1}{4}$ is $\frac{4}{9}$
