Answer:

Below in bold.

Step-by-step explanation:

Find the prime factors:-

126 = 2 * 3 * 3 * 7

234 = 2 * 3 * 3 * 13

Simple the expression <br> ( 3k + 4 1/5) + 8 3/5

lesantik [10]

Answer:

$3k+12\frac{4}{5}$

Step-by-step explanation:

$(3k+12\frac{4}{5})$

Convert mixed numbers to improper fractions:

$a\frac{b}{c}=\frac{a*c+b}{c}$

$4\frac{1}{5}=\frac{4*5+1}{5}$

$=\frac{21}{5}$

$=(3k+\frac{21}{5} )+\frac{43}{5}$

Add the fractions

$\frac{21}{5}+\frac{43}{5}$

$\frac{21}{5} \frac{43}{5} =\frac{64}{5}$

$=3k+\frac{64}{5}$

Divide 64 by 5

$\frac{64}{5}$ $12.8 or 12\frac{4}{5}$

$=3k+12\frac{4}{5}$
