You find the LCM of the denominators in the fractions, then you multiply both fractions as needed till both have like denominators. Then you subtract.
For example:
5/9 - 2/4
LCM of 9 and 4 is 36
[(5 x 4)/(9 x 4)] - [(2 x 9) - (4 x 9)]
= 20/36 - 18/36
20/36 - 18/36 = 2/36
2/36 = 1/18
hope this helps ya!
Answer:
) one complete revolution. Describe the solid determined by this revolution, and then find the volume of the solid.
Step-by-step explanation:
Answer:
(4, 1)
Step-by-step explanation:
Since the first reflection is over the vertical line x=-3, the y-coordinate remains the same. The x-coordinate of A' will make the point (-3, 4) on the line of reflection be the midpoint between A and A':
(-3, 4) = (A +A')/2
2(-3, 4) -A = A' = (-6-(-7), 8 -4) = (1, 4)
The reflection over the line y=x simply interchanges the two coordinate values:
A'' = (4, 1)
Answer:
Henry will get $15.77 back.
Step-by-step explanation:
20 - 4.23 = 15.77
Fractions need common denominator to add or subtract them because without denominators a fraction is not a fraction, it is a whole number
Example - 2/8 is a fraction
but 2 is not a fraction
