To get the value of y, the number to be multiplied on either side of the equation y10=32 is ____

The correct option is B 10y10=32Post multiply both sides by 10y10×10=32×10⇒y=3×5=15∴10 is the number to be multiplied on either side of the equation to get the value of y

To get the value of $y$ , the number to be multiplied on either side of the equation $\frac{y}{10} = \frac{3}{2}$ is ____

The correct option is B $10$
$\frac{y}{10} = \frac{3}{2}$

Post multiply both sides by $10$

$\frac{y}{10} \times 10 = \frac{3}{2} \times 10$

$\Rightarrow y = 3 \times 5 = 15$

$∴ 10$ is the number to be multiplied on either side of the equation to get the value of $y$
