There are two solutions: 1000 = 265 + 123 + 75 + 189 + 98 + 250, and 1000 = 265 + 312 + 75 + 98 + 250.
The numbers, when summed, are 75, 77, 79 and 81.
1*624, 2*312, 3*208 etc or 10*62.4, 20*31.2, 30*20.8 etc or 100*6.24, 200*3.12 etc Unless you want the square root of 624, which is ± 24.979992 (to 6 dp)
39 will go into 312 8 times
It is: 312*13 = 4056
9 x 312 = 2808
312 x 4 = 1248
The 10s times table is the easiest one of all! 312 x 10 = 3120 312 x 100 = 31200 312 x 1000 = 312000 312 x 10000 = 3121000
312 ÷ 35 = 8.91 (8 times with a remainder of 32).
312 multiplied by 45 is 14,040.
64 goes into 312 four times with 56 left over.
12 x 26 = 312
