I think you would look at lbs
The simplest way to do this is to get it into improper fraction form with the same denominator.
First things first, get it into an improper fraction.
7 7/8 = 7*8+7/8 3 1/4 = 3*4+1/4
= 56+7/8 = 12+1/4
= 63/8 = 13/4
The next thing to do is to get the denominators the same by finding the LCF, which could be done by dividing the 63/8 by 4, which would give a decimal as a numerator, so its best to multiply 13/4 by two
The two fraction will then be:
63/8 and 26/8
Seeing as the denominators are the same, you can simply subtract the numerators and simplify, i.e.
63-26/8 = 37/8
= 4 5/8
Hope this makes sense :D
Answer:
Volume of a cylinder = πr²h
Given
V=81π
r=3
find h
Making h the subject
h= V/πr² = 81π/π(3)²
h= 81/9
h= 9cm

For x=0
Answer:
Square root of 36.
Step-by-step explanation:
The square root of 36 = 6 so this is rational.
Recall that a rational number is one that can be written as a/b where a and b are not 0. 6 can be written as 6/1.
