Fractions and such. brainliest answers goes to whoever. and this is worth a lot of points. me.

6. mark and john were sharing the $10 cost to rent some video games with another friend. mark paid $3, john paid 2/5 of the total, and their friend paid the rest.

who paid the most towards the rental?
a. mark
b. john
c. the friend
d. all paid the same

1 is A. -1, because when dividing you multiply by the reciprocal, which is when you flip the numbers, so the denominator goes to the numerator and the numerator goes to the denominator. In 2, you convert both fractions to mixed numbers which gives you C. 32 1/5, or 32.2. In 3, you do the same thing except this time you pay attention to the sign, and because a positive* negative = negative, your answer has to be negative. Converting them to mixed numbers and multiplying you should get -73.11 repeating, and it seems that maybe your answer choices got mixed up. If it isn't the case, I will rework the problem. Number 4 would be 5/-3 because when solving you get 1.70, and 5/3 is 1.66 repeating. Number 5 is C. 1/2 because when multiplying you get 1/2. Number 6 is John because Mark paid $3, John paid $4, and the other friend paid $3. If you need me to explain anything more in detail please let me know. Hope this helps.
