Divide 33 into 2 groups so the ratio can be 4 to 7

To do this task the best way is always add both "sides" of ratio and divide whole group by this sum.sum=4+7=1133:11=3Now we know how much is 1 and we can multiply by 4 and by 7 to find the answer.3*4=12 - first group3*7=21 - second group
Your result is ok.

4:7added = 11

4/11(33) = 132/11 = 12
7/11(33) = 231/11 = 21

ur 2 groups are 12:21
