252 + x = 500 x = 500 - 252 x = 248

Because 252 is a multiple of 12, 12 and 252 are one pair (252 = 12 x 21 = 252 x 1)Another pair is 36 and 84 (252 = 36 x7 and 84 x 3)252 = 3 x 3 x 4 x 7 = 12 x 3 x 7, so only 36 and 84 are possible multiples of 12.
0.6 x 420 = 252
There are 60 minutes in one hour. Therefore, 3 hours 30 minutes is equal to (3 x 60) + 30 = 210 minutes.
252 = 1 x 252 252 = 2 x 126 252 = 3 x 84 252 = 4 x 63 252 = 6 x 42 252 = 7 x 36 252 = 9 x 28 252 = 12 x 21 252 = 14 x 18
252 + x = 500 x = 500 - 252 x = 248
The LCM, or least common multiple of 14 and 252 is 252. 14 x 18 = 252, and 252 x 1 = 252.
3 x 60 minutes = 180 minutes + 30 minutes = 210 minutes
70 percent of what number (call the number "x") is 252, so; 0.7 * x = 252 x = 252 / 0.7 x = 360

2 x 2 x 3 x 3 x 7 = 252
Because 252 is a multiple of 12, 12 and 252 are one pair (252 = 12 x 21 = 252 x 1)Another pair is 36 and 84 (252 = 36 x7 and 84 x 3)252 = 3 x 3 x 4 x 7 = 12 x 3 x 7, so only 36 and 84 are possible multiples of 12.
(3 x 60 x 60) + (30 x 60) = 12600 seconds.Therefore, there are 12600 seconds in 3 hours 30 minutes.
60 x 24 x 30 = 43,200
0.6 x 420 = 252
