Question

[2/(-3/7)]-[1/6*3/2]+1/4*2/5​

Answer 1

Answer:

-289/60

Step-by-step explanation:

[2×7/-3]-[3/12]+[2/20]

[14/-3]-[3/12]+[2/20]

-14/3 -3/12+2/20

Now,

take the LCM of3,12and 20 =60

-280-15+6/60

-295+6/60

-289/60

Answer 2

Answer:

-638/520 = -319/260(simplified)

Step-by-step explanation:

[2/(-3/7)]-[1/6*3/2]+1/4*2/5​

= [2/-3/7]-[1/4]+1/10 (when u simplify 1/6*3/2 it becomes 1/4) (when u simplify 1/4*2/5 it becomes 1/10)

= [2/1*-7/3]-1/4+1/10 (when u convert division sign into multiplication -3/7 becomes-7/3)

= -14/13-1/4*10+1/10*4 (multiply both in numerator and denominator)

=-14/13-10/40+4/40

= -14/13-6/40

=-14/13*40-6/40*13 ( multiply both in numerator and denominator )

= -560/520-78/520

=-638/520

=-319/260 (simplified)
