Cross multiply to get

We can use the cross multiplication formula.

Following the image's suggestions, we can plug in

We'd multiply

We'd then set the two values equal to each other:

To solve the equation ( \frac{s}{11} = \frac{30}{110} ) using cross products, you multiply the numerator of one fraction by the denominator of the other fraction and set them equal to each other. This process looks like this:

[ s \times 110 = 30 \times 11 ]

[ 110s = 330 ]

Then, to solve for ( s ), divide both sides of the equation by 110:

[ \frac{110s}{110} = \frac{330}{110} ]

[ s = 3 ]

So, ( s = 3 ).
