hopefully this helped
11 1/5 = (11*5+1)/5=56/5
2 3/4= (2*4+3)/4=11/4
11 1/5 : 2 3/4=56/5:11/4=56/5*4/11=(56*4)/(5*11)=224/55≈4.07≈4
Answer is 4

Answer:
7
Step-by-step explanation:
So, we know that this process happened 3 times in total. The original amount of kids we can call x, so the next wave filled in the gaps inbetween, so we call that amount x-1, the next wave would be (x+x-1)-1 or 2x-2, and the last would be 4x-4
adding this all up we get 8x-7=49, so 8x = 56 or x = 7
Sure, what are the questions?
