What is 2/9 = 4/x+8 i dont get this fraction solving

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$\frac{2}{9} = \frac{4}{x + 8} \\$

$\frac{4}{x + 8} = \frac{2}{9} \\$

Inverse both sides

$\frac{x + 8}{4} = \frac{9}{2} \\$

Multiply sides by 4

$4 \times \frac{x + 8}{4} = 4 \times \frac{9}{2} \\$

$x + 8 = 2 \times 9$

$x + 8 = 18$

Subtract sides 8

$x + 8 - 8 = 18 - 8$

$x = 10$

Done...

QveST [7]

We have been given that the slipperiness of a floor (demoted by S) can be defined as $S=\frac{P}{A}$

Here P= number or banana peels

A=area of the floor

Number of bananas peels can be measured (units ) in peels

Area can be measured in $m^2$

Since, slipperiness of a floor is the ratio of these two hence, we have

$\text{slipperiness of a floor}=\frac{\text{Peels}}{m^2}$

A is the correct option.
