To start this question, put all of the terms in the same unit. Yards and feet aren’t equivalent, but a simple multiplication can put them in the same unit (1 yard = 3 feet).
60 feet in 1.5 hours vs. 90 feet in 2.5 hours
Now, put the distance travelled by each in the same amount of time. You can reduce these to one hour each, or you can multiply both by a common denominator to save some fraction work (the first CD I can calculate is 30 hours, so multiply each fraction by the necessary number to bring the denominator to 30).
(60 feet/1.5 hours) x 15 = 900 ft/30 hours
(90 feet/2.5 hours) x 12 = 1080 ft/30 hours
1080 feet in 30 hours is greater than 900 feet in 30 hours, so 90 feet in 2.5 hours is faster than 20 yards in 1.5 hours.
Hope this helps!
Question: Please help lily team won 8 out of 12 games.At that rate,how many games will her team win if it plays 21 games?The ratio is now: 8 : 12 = X : 21, where x is the unknown value of win they have and 21 is the total number of games they played=> 8 : 12 = x : 21=> 8 * 21 = 168 / 12 = 14Thus, the new ratio is 8 : 12 and 14 : 21they will be winning 14 games out of 21 plays<span>

Answer: C
Step-by-step explanation:
120 plus 80 equals 200.
One way, for example, would be the following:
40/11 = 3.63
This handle shows that all students of Mrs. Wilson obtained the same number of points (3.63) to reach 40 points.
Note: there are many ways for 11 students to earn 40 points by making different combinations of notes.
