children in the form 1:n
*
can someone help me?

1 : 2.8

Step-by-step explanation:

in such a case what the question is asking you to is to compare the numbers and simplify them with the left hand number.

ratio of adult to children

write it as 5:14

put the 1 :n underneath

5  :  14   what we want to find is the n. among the 2 sides one is complete                      

1   :   n      only whole numbers. to get n look at the complete side . if

                    5:1      14=14 x 1 /5(cross multiplication). or you can

divide both sides by the left hand number(5)

5   and   14   =   1 :  2.8

5              5

the n is what we were trying to find and compare it to 1

this means for every 1 adult there are 2.8 children

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
