​

Answer 1

Answer:

12 boys in both the group and 9 girls in both the group.

Step-by-step explanation:

Total no.of boys=24

Total no.of girls=18

So, We have to divide them into two groups in which the no.of girls and boys will be same in both the groups.

So girls in each group = total no.of girls / total no.

of groups

= 18/2

=9

total no.of girls in both the group =9.

Now, similarly,

Boys in each group = total no.of boys / total no.of. groups.

=24/2

=12

Total no.of boys in both the group =12

Thus, total no.of girls in both the groups is 9 and total no.of boys in both the group is 12.

Answer 2

Answer:

greatest number of groups=6

Step-by-step explanation:

hcf of 18,24=6

then no. of groups=6

in one group

no. of boys =24/6=4

no. of girls=18/6=3
