A compound fraction is simplified by multiplying the numerator by the reciprocal of the denominator fraction. This process is repeated as often as necessary at every level of the fraction.
Examples:
(a/b)/(c/d) = (ad)/(bc)
a/(b/c) = (ac)/b
(a/b)/c = a/(bc)

When the fraction has numerators or denominators that are fractions, you need to be very clear about what is being divided by what. If it isn't clear by the typesetting (length or boldness of fraction bars), then parentheses are required around numerators and around denominators.
16 oz = 1 lb 1 1/4 lbs = 20oz 20+14+12+10= 56oz 56 divided by 8= 7
To find the y int, sub in 0 for x and solve for y
0 + 2y = 72
2y = 72
y = 72/2
y = 36....so ur y int is (0,36)
to find the x intercept, sub in 0 for y and solve for x
x + 2(0) = 72
x = 72....and ur x int is (72,0)
An equation that means 8 more than x is 14 would be x + 8 = 14. I hope this helps!

Actually Welcome to the Concept of the Differential Calculus.
Since, we know this is a definite calculus,
thus we get here as, by using the Chain Rule.
