Well first you would start by setting up with a proportion.
In total, the girls paid $54+$22= $76
Thus 1 sister contributed $54/$76=x/100
The other sister contributed $22/$76=x/76
For each proportion, cross-multiply and simplify to get the percentage. The percentage will be the x

Answer:
We want to divide 30 by it's half.
The half of 30 is 30/2 = 15
then we have: 30/15 = 2
Now we want to add the half of 18, that has ben divided by the half of the half of 12 hafter been divided by half.
The half of 12 is 12/2 = 6
the half of the half of 12 is 6/2 = 3
now, we wanto to divide the half of 18 by that number.
The half of 18 is 18/2 = 9
then we have 9/3 = 3
and we wanted to add this to the number previous found:
2 + 3 = 5
Answer:
Step-by-step explanation: Factors of 18: The square root of 18 is 4.2426, rounded down to the closest whole number is 4. Testing the integer values 1 through 4 for division into 18 with a 0 remainder we get these factor pairs: (1 and 18), (2 and 9), (3 and 6). The factors of 18 are 1, 2, 3, 6, 9, 18.
hope this helps ^-^
