You can solve for the variable by using the Cross Products Property.

54/11

Practice makes perfect

To solve the proportion, we will start by using the Cross Products Property.

6/11=x/9

Cross multiply

6 * 9=11* x

Multiply

54=11x

From here, we will continue solving for x by using the Properties of Equality.

54=11x

.LHS /11.=.RHS /11.

54/11=x

Rearrange equation

x=54/11
