Question

My cousin got 2/10 21/48 and 14/25 on her tests,what % will she get if that was 25% of her grade?

Answer 1

= the sum of the points you earned divided by the total points possible

= (2+21+14)/(10+48+25)

= (37/83)

= .446  This is the quantity of the grade that will account for a quarter of the total grade (25% of your grade will be a 44.6%)

The grade she gets depends on what she gets on the other 75% of the class.  

To figure this out use this equation

= [.75(the rest of the grades as figured out by the first equation I gave, the sum earned/total sum) + .25(.446)] * 100%

Hope this helps

Answer 2

80% on the first.

Now these don't make sense..

About 200% on the second and third.

I would recheck the math problem, I highly doubt that this is your cousin's. Hope I help! Good luck!

Answer 3

= 100%(25%[2/10 + 21/48 + 14/25])

= 100%(25/100[1/5 + 7/16 + 14/25])

= 100%(1/4[{80/400 + 175/400 + 334/400}/3])

= 100%(1/4[{589/400}/3])

= 100%(1/4[589/1,200])

= 100%(589/4,800)

= (100%/100)(589/[4,800/100])

= 1%(589/48)

= 589/48% or 12 13/48%

Answer: 12 13/48% or 12.27 1/12%

Answer 4

(20%+43.75%+56%)3=39.92%

Average for those three scores is 39.92%

39.92X25%=10%

Therefore she will get 10Percent of the 25% available
