Answer:
3/4 or 0.75 decimal
Step-by-step explanation:
Simplify the following:
(2/3)/(8/9)
Hint: | Write (2/3)/(8/9) as a single fraction.
Multiply the numerator by the reciprocal of the denominator, (2/3)/(8/9) = 2/3×9/8:
(2×9)/(3×8)
Hint: | In (2×9)/(3×8), divide 9 in the numerator by 3 in the denominator.
9/3 = (3×3)/3 = 3:
(2×3)/8
Hint: | In (2×3)/8, divide 8 in the denominator by 2 in the numerator.
2/8 = 2/(2×4) = 1/4:
Answer: 3/4
If you compare table values to answer choices, you can see right away that several don't work. The number of centimeters is greater than the number of inches, so adding to or multiplying the number of centimeters by some number more than 1 will not give you the smalller number that is inches.
While it may work for the first number (5 inches) to add 7.7 to get the first number of centimeters (12.7), you have to know that you can only add like to like. You can only add inches to inches (getting a result of inches), or centimeters to centimeters (getting a result of centimeters). From the point of view of the units involved, it is <em>nonsensical</em> to add a pure number to a number of inches and expect to get a number of centimeters.
So, we're down to the second choice:
- The number of inches is multiplied by 2.54 to find the number of centimeters.
_____
To find the pattern in the table, you can ...
- observe that the inch values differ by 1
- observe that the centimeter values differ by 2.54
- realize that the constant differences mean the relation between inches and centimeters is linear, and that a change in an inch value of 1 inch is multiplied by 2.54 to find the corresponding change in centimeter value.
_____

Answer:
N = 80
Step-by-step explanation:
of means multiply and is means equals
135% * N = 108
Change to decimal form
1.35 * N = 108
Divide each side by 1.35
1.35 * N/ 1.35 = 108/1.35
N = 80
