12.75
12.75 = 12 and 3/4 = 51/4
51 x 4 = 204
51
because 12.75 x 4 = 51
3 x 17
3 times 17 equals 51
1 x 51, 3 x 17, 17 x 3, 51 x 1
51 times with 4 remaining 616 - 4 = 612 = 12 x 51
3 times 17
4 goes into 51 12.75
You can put 15 into 51 three times, since 15 multiplied by 3 equals 45, which is less than 51. If you try to put it in four times, that would equal 60, which exceeds 51. Therefore, the answer is three times.
51 inches is equal to 4 feet 3 inches.
