3a^5 - (-a^5) = 3a^5 + a^5 = 4a^5
6a^7 - 2a^7 = 4a^7
-3a^5 - (-2a^5) = -3a^5 + 2a^5 = -a^5
7a^7 - 8a^7 = -a^7
For this you would do

Because 60% is the same as 0.60. And solving a problem like this is the opposite of finding a percent of a number. When you solve this you get 80. So there are 80 students in total.
Answer:
0.9
Step-by-step explanation:
14/15 = 0.933333333 <u>IF:</u>
<u></u>
<u>1.</u><em> You first change it into a decimal by dividing the numerator by the denominator.</em>
<em> </em>14 ÷ 15
<u>2.</u> <em>You will get a recurring decimal.</em>
<em> </em>0.933333333
<u>3.</u><em> The first digit after the decimal is in the position of the '</em><u><em>tenths'</em></u>
0.<u>9</u>
<u>4.</u><em> You should use only two digits after the decimal to calculate </em>
<em> 0.93</em>
<u>5.</u><em> Since the number 3 is less than five, it will change into a zero and get eliminated.</em>
<em> ∴ The answer will be = 0.9</em>
