The numerator of a fraction is 3 less then the denominator. If 1 is added to the numerator, the value of the fraction becomes 3/
andrew11 [14]

The fraction is \frac{5}{8}

Step-by-step explanation:

Let,

The denominator of fraction = x

Numerator of fraction = x-3

Fraction = \frac{x-3}{x}

According to given statement;

1 is added to the numerator, the value of the fraction becomes 3/4.

\frac{x-3+1}{x}=\frac{3}{4}\\\\\frac{x-2}{x}=\frac{3}{4}

Using cross multiplication

4(x-2)=3*x\\4x-8=3x\\4x-3x=8\\x=8

Fraction = \frac{x-3}{x}=\frac{8-3}{8}=\frac{5}{8}

Keywords: fraction, division

How to solve this equation
mariarad [96]
\bf \sqrt{5x+19}-4=3x-15
\\\\
\sqrt{5x+19}=3x-15+4\\\\ \sqrt{5x+19}=3x-11\leftarrow \textit{square both sides}
\\\\
(\sqrt{5x+19})^2=(3x-11)^2
\\\\
5x+19=(3x-11)^2\qquad 
\begin{cases}
(3x-11)^2\to (3x-11)(3x-11)\\
 --------------\\
\textit{or use FOIL to expand it}
\end{cases}

then solve for "x"
