Answer:
0.4 or 2/5???
Explanation:
I believe this is a proportion/ratio problem.
Think of it like this:
x/6 = 10/150
To solve for x, you must cross multiply:
150x = 6*10 (150x... DON'T write 150*x, that is nonsense)
150x = 60
x = 60/150 (you divide because you are actually dividing 150 on both sides and doing the opposite operation of multiplication)
x = 6/15
x = 2/5 or 0.4 (I simplified it)
Hopefully this helped? I can't seem to find a whole number answer... so the only options I could do are 2/5 or 0.4
