If
![\frac{6}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B7%7D)
were incorrect, it means that
![\frac{1}{7}=4](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7D%3D4)
were correct
![4*7=28](https://tex.z-dn.net/?f=4%2A7%3D28)
There were 28 problems ;)
Answer: 3
Step-by-step explanation: Because, 1/2=2/4=3/6=4/8=5/10=6/12 are all the same. You can test is out by simply factoring out the biggest factor on both sides. For example, 2/4 can be simplified to 1/2, because 2/4=(2/2)/(4/2) you can divide both sides by two. Hope this helps, <3!
LCM is found by finding the factors of both and making sure that both are inthere
9=3 times 3
12=2 times 2 times 3
common one is 3
so we have to have at least 2 threes and 2 twos
2 times 2 times 3 tiimes 3=36
answer is 36
