hi friend, mark my answer brainliest for further help and support

Step-by-step explanation:

(\frac{7}{12}*\frac{3}{14})  +  (\frac{3}{5} *\frac{6}{15})\\\\=> (\frac{1}{8})  +  (\frac{6}{25})\\

now we take lcm

lcm= 25*8 = 200

\frac{25+48}{200} \\\\=\frac{73}{200} ------------------------------------------- ( Answer for part a)

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(\frac{13}{21} /  \frac{39b}{42})*b* \frac{-5}{5}

(\frac{13}{21} *\frac{42}{39b} )*-b

\frac{2}{3b} *  -b

\frac{-2}{3}--------------------------------------------------(Answer for part b)

Answer:

Step-by-step explanation:

7/12 x 3/14 = 1/8 simplification

3/5 x 6/15= 18/75 no simplification

18/75 + 1/8=

18x8/75x8 + 1x75/8x75

=  144/600 + 75/600

= 69/600

= 11/100

And I hope it helps
