It's 8% because if you write out .4 of 4.9=___, that equals to .4/4.9=x/100 which is basically .5/5=x/100. Then, since 5x20=100, that means .5x20=x. You would get 8.
1 liter = 1000 ml......so 6,008,835,000 = 6,008,835,000 / 1000 = 6,008,835 liters
so it takes 6,008,835 liters per second
and (6,008,835 * 60) = 360,530,100 liters per minute
The word product tells us that we will be multiplying, the word "of" is where the multiplication sign goes, the word "is" is where the equals sign goes, and Mai's score is the unknown, x. In equation form, then, that would look like this:
2x=32
the product of 2 and Mai's score is 2 times x or 2x; "is" means equals. There you go!
