please do number 15 and 16
I don't really understand it so; please do it with step by step
thanks in advance ​

Answer 1

Answer:

For the first one you need to try and arrange and we can place all the pieces on the board so answer is 15.

(P.S sorry i cant show you how to do it)

Step-by-step explanation:

For the second one its trial and error

I found out that total 7 sisters and 5 brothers fit so 13 children

Answer 2

15.just place the last piece at the bottom,followed by the first piece at second and he middle most piece must be placed at top

this gives u your answer...and if u aren't able to find your answer then just count the total number of squares.  (LOL,sometimes it works)

ans:15

16.no of brothers of J=x

no of sis=2+x

total children=x+x+2------1

for mark

brothers=x-1    (as he himself is one of the brother of judy)

sisters=2(x-1)

total=x-1+2(x-1)-------2

since number of children remains same

1=2

2x+2=x-1+2(x-1)

2x+2=3x-3

x=5

therefore brothers are 5 and sisters are 7

hope this helps

plz mark as brainliest
