Which is a better test score:
121/150 or 28/35
How do I figure?
didvide 125 by 150 which gives u .80 which means 80% and divide 28 by 35 qhihc gives u 80% again which means they're both good
I see two ways to do this. Pick whichever you prefer.
One simple way is to divide the fractions, bottom into top, to get a decimal.
A slightly cleverer way, in this case, is to look at the second and reduce it to its lowest terms - divide top and bottom by 7 to get a vary familiar fraction: 4/5.
Now look at the other fraction. What would 4/5 of 150 be? When you see that, you'll know immediately which is slightly bigger than the other.
To determine which test score is better, you need to compare the fractions in a way that allows for an equal basis of comparison. In this case, you can convert both fractions to a common denominator and compare the numerators.
To find the common denominator, you need to find the least common multiple (LCM) of the denominators, which in this case is 150 and 35. The LCM of 150 and 35 is 1050.
Now, let's convert the fractions to have a denominator of 1050:
121/150 can be converted to (121/150) * (7/7) = 847/1050
28/35 can be converted to (28/35) * (30/30) = 840/1050
Now that both fractions have the same denominator, you can compare the numerators.
847/1050 is greater than 840/1050, which means the test score of 121/150 is better than 28/35.
