Answer:
(i) 14 groups
(in) 15 boys per group and 16 girls per group
Step-by-step explanation:
(i) After the withdrawal of the 4 boys and 6 girls, there are 210 boys and 224 girls left. To find the greatest number of groups that can be formed with an equal number of boys in each group and an equal number of girls in each group, you need to find the GCF (Greatest Common Factor) of 210 and 224. Since 210 is 2 * 3 * 5 * 7 and 224 is 2^5 * 7 the GCF of these two numbers is what they have in common which is 2 * 7 which is <u>14</u>. Thus, 14 is the greatest number of groups that can be formed.
(in) When 14 groups are formed, there are 210/14 boys in each group and 224/14 girls in each group. That results in <u>15</u> boys per group and <u>16</u> girls per group.
Hope this helps :)

I don't know if you are supposed to find the green but then it would be
16(pink): green(I don't know the green)
If you don't know the green I guess it would be 16:x. X stands for green.
