What is the value of 8/15÷(-0.35) a -75/14 b -32/21 c -21/32 d -14/75 i would really appreciate it if you could also explain how

Answer;-1.5238095238
First step; 8/15

8/15 = 0.53 and so on in a repeating form. (0.53333333333)

Divide; 0.53 / -0.35 

= -1.5238095238

Remember, when dividing fracitons, invert and multiply or
(a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)

also, (+)/(-)=(-)

convert -0.35 to fraction
-0.35=-0.35/1=-3.5/10=-35/100

now we have
(8/15)/(-35/100)
we know the end result is negative so discard that
(8/15)/(35/100)
35/100 simpifies to 7/20
(8/15)/(7/20)
invert ane multiply
(8/15)(20/7)
(8*20)/(15*7)
160/105
32/21
negative
-32/21
