Taking equal groups, in our case, 7 out of the whole number, in this case 364 involves guessing. A shorter method involves taking groups, in our case, 7 out of each individual number 3, 6 and 4. If you cannot take 7 out of a number, you will subtract 0 from that number and carry down the next number. For example, you cannot take 7 from 3, so you will subtract 3-0 with the answer being 3 and carry down the next number, 6, giving you 36. You can take 5 groups of 7 out. 5 groups of 7 equals 35, leaving you with a 1 left over, (36-35). you will then carry down the next number next to the 1, in this case 4, making the final number 14. You can take 2 groups of 7 out and 2 groups of 7 equals 14, leaving you with no left over groups. so your answer will be 52.
