Given ratio : 90 lbs on earth :15 lbs on the moon.
Let us write 90 lbs :15 lbs in fractions first.
90:15 = 90/15
Now, in order to determine different strategy, we need to find any equivalent fraction/ratio of the given fraction or ratio.
In order to find an equivalent fraction or ratio, we need to find a common number that can divide( even we can multiply) both numerator (top number) and denominator (bottom number).
For the given ratio 90/15, we can divide 90 and 15 both by 15.
90 ÷ 15 = 6
15 ÷ 15 = 1
Therefore, 90 lbs on earth :15 lbs on the moon could be written as 6 lbs on earth :1 lbs on the moon.

Answer:
a. A frame is a list of individuals in the population being studied.
Step-by-step explanation:
We are asked to choose the correct definition of frame from our given choices.
We know that a frame, in statistics, is a list of all those within a population who can be sampled. It may include individuals, households or institutions.
We also know that a frame is the source material or device from which a sample is drawn.
Upon looking at our given choices, we can see that option 'a' is the correct choice.
X^2 + 3x - 28 factors to (X+7)(X-4)
X^2 - 7X + 12 factors to (X-4)(X-3)
Now we see that the equation is [(X+7)(X-4)]/[(X-4)(X-3)]
By dividing the top and bottom by (X-4), we see that the equation equals (X+7)/(X-3).
