50 x 90 = 4500
x/y*100=% For example: 45/90*100=% 1/2*100=% .5*100=% 50=% Check: 50% of 90 = x 50/100 * 90 = x .5 * 90 = x 45 = x
50 - 90% = 50 x (1 - (90/100)) = 50 x 0.1 = $5 Therefore, 90 percent off 50 dollars is equal to 5 dollars.
The greatest common factor of 90 and 50 is 10.10 x 5 = 5010 x 9 = 90
0.5556
90 cm x 50 cm = 697.5014 sq. inches.
50/90 x 100 = 55.5 recurring (that is, 55.5555...) percent.
Suppose the angle is x. Then its complement is 90-x x - 50 = 90 - x or 2x = 140 so that x =70.
To translate the question into an algebraic expression, we write 90% as 0.9 and create the variable x to represent the number in question. 0.9 * x = 45 x = 45 / 0.9 = 50. To verify, 90% of 50 is 45.
90 10 x 5 = 50 8 x 5 = 40 50 + 40 = 90 or 20 - 2 = 18 20 x 5 = 100 2 x 5 = 10 100 - 10 = 90
a mile = 1.6 km 50 x 1.6 = 80 So 90 Km is bigger
I presume you are asking for the equivalent single percentage discount when first 50% is applied, then 10%, then 10%, then 5% then 5%, ie 95% of 95% of 90% of 90% of 50% of the original price is being paid, so the total discount is 100% - this: 95% of 95% of 90% of 90% of 50% = 95/100 x 95/100 x 90/100 x 90/100 x 50/100 = 3655125/10000000 = 36.55125 % ≈ 36.55 % So the discount is approx 100% - 36.55% = 63.45 %
45/50 x 100 = 90%
