Andrew answered 21 out of 25 questions correctly on his math test. Written as a decimal, what portion of Andrew's answers were c
soldier1979 [14.2K]
Since we are calculating the amount that he got correct, we must divide the numerator by the denominator or make the denominator equal 100. I will do it the second way as it is easier in this case.

25*4 = 100
21*4 = 84

84/100 = 0.84

As a decimal, Andrew got 0.84 of his test correct. Hope this helps!

7+3√5/3+√5 - 7-3√5/3-√5​
Irina-Kira [14]

Answer:

0

Step-by-step explanation:

We can write the equation in a simpler form so it doesn't look like a mess of numbers:

7+\frac{3\sqrt{5}}{3}+\sqrt{5} -7 -\frac{3\sqrt{5}}{3}-\sqrt{5}

Because we are just adding three terms together and then subtracting those exact terms, we have the answer as 0.
