Firstly you need to to reduce to a common denominator by multiplYing the whole fraction. This way you have to multiply 4/5 by 2 (both numerator and denominator). so 4/5 = 8/10. And now you have 8/10 and 9/10. You compare only numerators. This way you have 8/10 <9/10. Same goes for 2/3 and 5/8. Only here you need to multiply both fractions. The common denominator here is 24. So you have to multiply 2/3 by 8 and 5/8 by 3. You now have to compare 16/24 and 15/24. 16/24>15/24.
        
             
        
        
        
<h3><u>The unknown number is equal to 4.</u></h3>
8x - 27 = 5
Add 27 to both sides.
8x = 32
Divide both sides by 8
x = 4
 
        
        
        
Answer:
<h3>-cos10°</h3>
Step-by-step explanation:
cos is positive at first and fourth quadrant
so, cos (-x) = cos (x)
also, cos(180-x) = -cos x
         cos (180+x) = -cos x
cos (-170°) = cos (170°)
cos(170°) = cos (180° - 10°)
               =  - cos 10°
