A business is owned by 3 people. Mrs. Applegate owns
Bezzdna [24]

Given:

Mrs. Applegate owns  \dfrac{3}{19} of the business.

Mrs. Brown owns 3 times as much as  Mrs. Charles.

To find:

The  fractional part of the business that Mrs. Brown owns.

Solution:

Let Mrs. Charles owns x part of business.

Mrs. Brown owns 3 times as much as  Mrs. Charles.

Mrs. Brown owns = 3x part of business.

Mrs. Applegate owns  =\dfrac{3}{19} of the business.

x+3x+\dfrac{3}{19}=1

4x=1-\dfrac{3}{19}

4x=\dfrac{19-3}{19}

4x=\dfrac{16}{19}

Divide both sides by 4.

x=\dfrac{16}{4\times 19}

x=\dfrac{4}{19}

Now,

Mrs. Brown owns  =3\times x

=3\times \dfrac{4}{19}

=\dfrac{12}{19}

Therefore, Mrs. Brown owns  \dfrac{12}{19} of the business.
