Answer 1

2/7x9/3+2/6/3/5-2=
2/7x 9/3 = 18/21 
2/6/3/5 = 2/6x5/3 = 10/18
18/21+10/18 - 2 = 
6/7+5/9 - 2
mmc de 7 e 9 = 63
54+35-126/63 = 89-126/63
= -37/63 

Answer 2

Bom dia

2/7 * 9/3 + (2/6)/(3/5) - 2 

= 3*(2/7) + (1/3)*(5/3) - 2

= 6/7 + 5/9 - 2 =
= 54/63 + 35/63 - 126/63 
= 89/63 - 126/63 
= -37/63
