We have the following fraction: (5) / (10) In order not to alter the expression, we must multiply the numerator and denominator by the same factor k: (5 * k) / (10 * k) Since we know that the denominator is 100 then: 10 * k = 100 Clearing: k = 100/10 k = 10 Substituting: (5 * 10) / (10 * 10) Rewriting: (50) / (100) Answer: The fraction that is equivalent to 5-10 and has a denominator of 100 is: (50) / (100)
The second one, Amanda's method is linear because the number of minutes increased by an equal number every week. Billy's method is linear because the number of minutes increased by an equal factor every week.
