Hello!
First of all, let's add 50 to both sides.
x/-3=50
Now we multiply both sides by -3.
x= -150
I hope this helps!
(a/b) / (c/d) = (a/b)*(d/c) that is the rule so:
(3/4)/(3/16) is equal to:
(3/4)*(16/3) which is equal to
16/4
4
(a) is the first one. 48 I would say 8 mins
(b) is the second one. 10 I would say is 96
