It would be: -2/3 * -9/10 = 18/30 = 3/5
So, option B is your answer.
Hope this helps!
15/100=0.15
45/0.15=300
so 45 is 15% of 300
The answer is points B.C.and D are on line n
Another basic one
(1/2)^2*1/2*(1/2)^3=
(1/2)^6 =
1\2^6=1/64
if in decimal: 0.015 but i would prefer 1/64 if i was the teacher :)
