Answer:
answer is 3/13
Step-by-step explanation
=3/5×(-1/4 -1/6) ÷ (-7/3 + 5/4)
=3/5×(-1*3/4*3 -1*2/6*2) ÷ (-7*4/3*4 + 5*3/4*3) (LCM of -1/4 -1/6 is 12 and =lcm of -7/3+5/4 is also 12)
=3/5 (-3-2/12)÷(-28+15/12)
=3/5(-5/12)÷(-13/12)
=-15/60 ÷-13/12
this can also be written as -15/60/-13/12
= -15/60×12/-13 than by cansaling we get
= -3/-13 (- and - get cancel )
=3/13
