Solve each proportion​
mamaluj [8]

Hello.

In order to solve a proportion, you should cross-multiply:

\displaystyle\frac{7}{x} =\frac{5}{9}

Multiply 7 times 9 and 5 times x:

5x=63

Divide both sides by 5:

x=\displaystyle\frac{63}{5}

Now let's solve the second proportion.

Multiply 8p times 6 and 12 times 15:

48p=180

Divide both sides by 48:

p=3.75

I hope it helps.

Have an outstanding day.
