Question

Petra eats five and three fifths pies in a pie-eating contest. Paulie eats three and fourteen sixteenths pies in the contest. How many more pies did Petra eat?
one and fifty eight eightieths pies
one and seventeen twenty firsts pies
two and fifty eight eightieths pies
two and seventeen twenty firsts pies

Answer 1

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)

$5 \frac{12}{20} - 3 \frac{5}{20}$

Make These Into a Mixed Fraction

$\frac{112}{20} -\frac{65}{20}$

Subtract 112-65

$\frac{47}{20}$

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

$2 \frac{7}{20}$

I think this is right. Hope This Helps
