try 11 times (practicing your time tables will be a great help later on)
33 x 33/3 = 33 x 11 = 363
3 * 3 / ( 3 * 3 ) = 1 but that uses only four 3s, so 33 / ( 3 * 3 * 3 ) = 1 uses five 3s
33 + (3/3)
28 3s
Use two of the 3s to make 33. Then: 33 - 3 = 11 11 + 3 = 14
To determine how many times 3 goes into 33, you would perform division. 33 divided by 3 equals 11. Therefore, the number 3 goes into 33 exactly 11 times.
33
33 x 33/3 = 33 x 11 = 363
3 + .3 + .33
It could be: 33-(3+3) = 21
3 * 3 / ( 3 * 3 ) = 1 but that uses only four 3s, so 33 / ( 3 * 3 * 3 ) = 1 uses five 3s
33/3 = 11
33 + (3/3)
28 3s
There are infinitely many. Some are: 4/6, 20/30, 22/33, 202020/303030, 2044/3066
Use two of the 3s to make 33. Then: 33 - 3 = 11 11 + 3 = 14
To find out how many 3s go into 140, divide 140 by 3. This gives you approximately 46.67. Since we're looking for whole 3s, you can fit 46 complete 3s into 140.
