Answer:
the first problem has infinite solutions, the second has one, and the third also has infinite solutions!
This is 2/21. You can simplify the 4 in -4/7 to 2 and the 6 in -1/6 to 3. So it would now be -2/7 times -1/3. A negative times a negative is a positive, so the answer will be positive. 1 times 2 is 2 and 7 times 3 is 21. 2/21
10=2x5
60=2x2x3x5
2x2x5x3=60
i think to do this you need lcm but im not sure
91 / 7
7 fits within 9 only once, so the first number is 1
you have two left over
drop the one from 91 down, so you have to figure out how many times 7 goes into 21
it goes in 3 times
so the answer is 13

29 - 82
since 82 is bigger than 29, you will be getting a negative number.
if you did 82 - 29 it would be 53
but after you hit zero, it is 52 below zero, so the answer is -53
