1/3 in 6th grade......1/3 = 0.33 = 33% in 6th grade
35% in 7th grade
(100% - (33% + 35%) = 100% - 68% = 32%

most students : 7th grade

All you have to do is divide each one by its other number.  For example, 5.60 for 8 is the same as one for 0.70.  We accomplish this by dividing the 5.60 by 8.
So...
0.70
0.80
0.90
0.75
The first choice is the lowest.

I need help ASAP!!

Answer:


\frac{64}{49}


Step-by-step explanation:


As we can see the given expression as three complex parts and all are being multiplied.


Lets simplify each part separately and then multiply all of them in the end


Part1


(\frac{8.4.2}{8.7})^{2}  

Cancelling 8 in numerator with 8 in denominator


(\frac{4.2}{7})^{2}


(\frac{8}{7})^{2}


\frac{64}{49}


Part2


(\frac{8^{0} }{7^{-3} })^{3}


simpliying


(\frac{1}{7^{-3} })^{3}


({7^{3} })^{3}


7^{9}


Part3


Third part is 7^{-9}, and it does not need to be further simplified


Now multiplying all the three parts


\frac{64}{49}.7^{9}.7^{-9}


\frac{64}{49}.7^{9-9}


\frac{64}{49}.7^{0}


\frac{64}{49}.1


\frac{64}{49}


So our final answer is \frac{64}{49}
