Take your pick:
15 is the only number which is a product of 2 primes (3*5).
63 is the only number that is the products of three odd primes (3*3*7)
8 is the only cube number (22)
50 is the only number that is not one less than a square number (15=42-1, 63 = 82-1, 8 = 32-1).
63 All the others end in 0
Of 63/0.15 = 420
31.5
63
3 = 63/21 = 150/50
The GCF of 15, 24, and 72 is 3. There is no GCF for 63, 20, and 50. This makes it relatively prime.
63
The answer is 63. This is because 5 tens = 50 and 13 ones is 13. Then, add 50 and 13, and you get 63.
not by a whole number 15 x 4 = 60 15 x 5 = 75 63/15 = 21/5 = 42/10 = 4.2
1 is the only integer.
x + 3(x+1) = 63; x + 3x + 3 = 63; 4x = 60; x = 15. 15 + 3 x 16 = 15 + 48 = 63. The Numbers are 15 & 16.
63 is 420% of 15. (63/15 * 100 = 420)
