Answer:
2 7/20
Step-by-step explanation:
So Lets put these into a fraction form
Petra: 5 3/5
Pauline: 3 4/16 -> Can be Simplified = 3 1/4
Take the number of pies Petra Ate and subtract it by the number of pies Pauline ate
Change the numbers to a common factor. (multiply 3/5 by 4 and 1/4 by 5 to have common denominators)

Make These Into a Mixed Fraction

Subtract 112-65

Simplify (divide 47 into 20 how many times to get into a mixed fraction)

I think this is right. Hope This Helps
Lets say you have 5x5. you would just add 5+5+5+5+5. To get a whole number for a fraction you have to do this. lets say you have 8/8 that would be equal to 8 circles and eight of those circles would be shaded in. 8/8 is one whole also 7/1 is a whole. It all depends on the problem you are trying to figure out
Answer:
see explanation
Step-by-step explanation:
These are the first 4 terms of a geometric sequence with n th term
= a₁ 
where a₁ is the first term and r the common ratio
r = 36 ÷ 24 = 54 ÷ 36 = 81 ÷ 54 = 1.5 and a₁ = 24, hence
= 24
