$\frac{2}{9} + \frac{1}{5}$

Required

Which step contains the first error?

From the attachment, the first step is the first error.

This is so because the fractions can not be written as a fraction with a denominator of 14

Solving further:

$\frac{2}{9} + \frac{1}{5}$

Find Common Denominator 45

$\frac{2*5}{9*5} + \frac{1*9}{5*9}$

$\frac{10}{45} + \frac{9}{45}$

Add:

$\frac{10 + 9}{45}$

$\frac{19}{45}$
