These problems are what is known as changing a mixed fraction to an improper fraction. Lets start with 5 1/8.
What we want to do is take the big number on the side and add it to the top of the fraction in a special way to make it an improper fraction. (An improper fraction means a fraction with a bigger top than bottom).
To add 5 to 1/8, we have to multiply 5 by 8 and then add it. 5 times 8 is 40 so if we add that to the top we know that the improper fraction we are looking for is 41/8.
We can do the same thing for 3 4/12, multiply 3 by 12 and add it to the top of the fraction. 3 times 12 is 36, add that to the top to get 40/12.
See if you can do 1 6/12 and comment with an answer, if you get it wrong I will keep helping you till we get this down!
4 days
donvert 3 and 1/3 to imporopoer
3 and 1/3=3+1/3=9/3+1/3=10/3
divide 10/3 by 4
remember that divide by 4 means multiply by 1/4
10/3 times 1/4=10/12=5/6

ANSWER for 2 is B I do not know the rest
I'm assuming the whole length is 18 ft.
Let x and y be the shorter and longer sides respectively.
x + y = 18 (shorter + longer side equals the whole length of the pipe)
2x = y - 2 (2 times the shorter piece is equal to 2 less than the longer piece)
x =
You can solve it simultaneously to find x and y.
