The answer is 9.
Aside from zero (0x0 = 0), the first 6 squares of integers are 1, 4, 9, 16, 25, and 36. 1 x 1 = 1 2 x 2 = 4 3 x 3 = 9 4 x 4 = 16 5 x 5 = 25 6 x 6 = 36
If the smallest number is x, the the largest one is 25 - x. So we have: (2/3)x = 2 + (1/4)(25 - x) 2x/3 = 2 + 25/4 - x/4 multiply both sides by 12, the common denominator; 8x = 24 + 75 - 3x add 3x to both sides; 11x = 99 divide by 11 to both sides; x = 9 So the smallest number is 9, and the largest number is 16 (25 - 9)
If the order of choice does not matter, the expression is 25 X 24 X 23 X 22 X 21 X 20 X 19 X 18 X 17, which can also be written as 25!/16!.
x = + or - 9 x/9 = 9/x x squared = 81 x = +/- 9
25 x 9 = (20 x 9) + (5 x 9)20 x 9 = 1805 x 9 = 45180 + 45 = 22525 x 9 = 225
x = (-25) x/5 + 9 = 4 (multiply both sides by 5) x + 45 = 20 x = -25 Checking: (-25)/5 + 9 = 4 gives -5 + 9 = 4 correct
3 x 3 = 9 5 x 5 = 25
25 x 9 = 225
9% of a number equates to 9/100 of that number. 9% of 25 is, 25 x 9/100 = 9/4 or 2.25 9% of 25 = 2.25
To convert a fraction to a percentage multiple by 100: 9/25 = 9/25 x 100 % = 36 %
25/9 x 100 = 277.7 recurring (that is, 277.7777...) percent.
25 x 2/9 = 55/9
9 x 1 = 9 9 x 2 = 18 9 x 3 = 27 9 x 4 = 36 So reduce 9/36 to 1/4 100 per cent divided by 4 equals 25 Answer: 25%
9 out of 25 is the same as 9 divided by 25 (9/25). 9/25 = 0.36To convert the decimal result to a percentage simply multiply it by 100: 0.36 x 100 = 36%
Assuming the numbers are in metres! 25 × 9 = 225 square metres.
2 x 9 x 25 = 450
