Answer:
1/24
Step-by-step explanation:
5/12 - 3/8=?
The first step is to find a denominator (bottom number) that is the same for both fractions. In this case, 24 works.
10/24 - 9/24 = ?
1/24
Step-by-step explanation:
1 Remove parentheses.

Done
So.
.
Let's get started with formulas.
.
I KNOW you hate formulas!! So do I, but we have to use them. No "buts".
.
So, how many minutes are in 2 weeks?
.
Search it up. For your convenience, it is 20,160 minutes.
.
Well, I think you have your answer, since each quiz is 5 minutes, 5 times 50 (5 x 50) is 2,500 minutes.
.
Yes, you can do 50 quizzes and MUCH MUCH more in 2 weeks.
.
Hope I helped!!
