Question

90% x z=81.9, find the value of z​

Answer 1

Step-by-step explanation:

$= > \frac{90}{100} \times z \: = \: 81.9$

$= > z \: = \: \frac{81.9}{ \frac{90}{100} }$

$= > z \: = \: 81.9 \: \times \: \frac{100}{90}$

$= > \: z \: = \: \frac{819}{10} \times \frac{10}{9}$

$= = = > \: z \: = \: 91$
