B. 12 + 3/4
C. 12 - 3/4
D. 12 divided by 3/4
I have narrowed it down to A and D. Now i am confused which one. please help me
Which method gives you a reasonable answer?
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.
12 * 3/4 is right.
1 week used 3/4
12 weeks ____ ?
12 x 3/4
so the answer is A
I think its D, but i also think its A.
So it is A?
Isn't that what I indicated?
Abablallaa la caca
it’s A 🤣🤞
To find how many bottles of hand sanitizer the students will use in 12 weeks, we can multiply the amount of hand sanitizer used per week (3/4 of a bottle) by the number of weeks (12).
So, the correct expression is:
A. 12 x 3/4
To solve this expression, you multiply:
12 x 3/4 = 36/4 = 9
Therefore, the students will use 9 bottles of hand sanitizer in 12 weeks.
Option D, "12 divided by 3/4", would give you the total number of weeks that can be covered by a single bottle of hand sanitizer, which is not what the question is asking.
Thus, the correct answer is A. 12 x 3/4.
