800/2300 = 0.3478260869565217

0.3478260869565217*100 = 34.78260869565217

34.78%

I'm asuming you mean 9 added to the fraction 2/8. That is easy: 2 is a quarter of 8 meaning that equels 0.25 add that to 9 and you get 9.25. In fraction form that is 9 and 1 4th

If you mean 2 divided by 8+9 then that is 0.117647058824........ in decimal form

There is no last digit. It is also known that it doesn't repeat; if it did it would be a rational number, but it is known to be irrational.

Yes, you just have to square the numerator and the denominator. For example, (¼)^2= 1^2/4^2, or 1/16.

(3/7)^2 = (3^2/7^2), or 9/49.

Your mistake is in step 2. You cannot combine two terms into one as you have it done, because:2(-20) + 3(-25) DO NOT equal: (3 + 2)(-20 + -25). Evaluate each term separately thus:( -40) + (-75)=-115. The way you have them combined comes to: 5 x (-45)=-225. A difference of -225 - (-115)=-110. The same applies to the last 2 terms. You must evaluate each term separately. That way you can't go wrong. The above answer of 185 appears to be right.

Simplify the following:
2 (-20)+3 (5/4 (-20))+5×2/5×50+4×50

5/4 (-20) = (5 (-20))/4:
2 (-20)+3×(5 (-20))/4+5×2/5×50+4×50

2/5×50 = (2×50)/5:
2 (-20)+3×(5 (-20))/4+5×(2×50)/5+4×50

3×(5 (-20))/4 = (5 (-20) 3)/4:
2 (-20)+(5 (-20) 3)/4+5×(2×50)/5+4×50

5×(2×50)/5 = (2×50×5)/5:
2 (-20)+(5 (-20) 3)/4+(2×50×5)/5+4×50

(-20)/4 = (4 (-5))/4 = -5:
2 (-20)+5×-5×3+(2×50×5)/5+4×50

(2×50×5)/5 = 5/5×2×50 = 2×50:
2 (-20)+5 (-5) 3+2×50+4×50

2 (-20) = -40:
-40+5 (-5) 3+2×50+4×50

5 (-5) = -25:
-40+-25×3+2×50+4×50

-25×3 = -75:
-40+-75+2×50+4×50

2×50 = 100:
-40-75+100+4×50

4×50 = 200:
-40-75+100+200

-40-75+100+200 = (100+200)-(40+75):
(100+200)-(40+75)
300-(40+75)
300-115

You immerse it in a well-graded container full of water. You ckeck the volume of water carefully BEFORE and AFTER the immersion of the object. The difference between the two is the VOLUME of the object. And, if you want to find its density, then you divide 5 kg/ volume. Make sure the units are consistent,
