Aww what a cutie ok heres a freebie
find your lowest common denominator which is 35 then 5 x 7 is 35 7 x 3 is 21. 21/35. Now solve for 6/7 same way 7 x 5 is 35 so 7 x 6 is 42/35. 42 + 21= 53/35 this is your answer teacher will want you to show your work i cant do it on this junk phone. If your answer had of been 2/4 then reduce to 1/2 in your case 53 is an odd number and cant be reduced because to reduce means both numbers have to be divided by the same number 2/4 both divisible by two. Also in division any number ending in two o an even number is always divisible by 2 learn math shortcuts it will help you. Also a lowest common denominator is any number that your two bottom denominators such as 7 + 5 can both go into thats why you had 35 its the lowest number that 7 + 5 can go into. I hope this helps. Algebra was hard for me in school because my teachers sucked. A good teacher can show you varius methods to each your desired answer. My advice to you young lady is to learn it good because its your future.

3/5 divided by 6/7
is the same as
3/5 TIMES 7/6
NOTE that through cross-cancelling, 3 goes into 3 once and into 6 twice
1/5 TIMES 7/2
(1)(7) / (5)(2)
7 / 10
can't simplify further

multiply by reciprocal of denominator:
(3/5)(7/6) = (1/5)(7/2) = 7/10
(3/5)(7/6) = (1/5)(7/2) = 7/10

(3/5)÷(6/7),
(3/5)(7/6),
21/30,
simplify,
7/10.
Answer: 7/10.
(3/5)(7/6),
21/30,
simplify,
7/10.
Answer: 7/10.

you flip the second fraction and then multiply it. ex. 3/5 divided by 6/7 flip 6/7 so it becomes 7/6 then multiply. 3/5 x 7/6 =21/30

I believe SUN already has the best answer. I was going to do the same thing , but with instructions.
