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)

when a negative number adds a negative number, it will be negative
when a negative number adds a positive number, whichever number (either positive or negative) take the sign of the bigger one
For example:
-4 + 3 = -1
-5 + 10 = 5

Answer: 1/10
Step-by-step explanation:
given:
numbers contained in the i.d
1,4,3,7,6
1. permutations of 5 possible outcome
T = 5
= 5 * 4 * 3 * 2 *1
= 120 times.
2. permutations of 3 odd numbers
( 1,3 and 7 )
T = 3
= 3 * 2 * 1 * 2 * 1
= 12
probability of of first three digits being odd numbers
P = 12 / 120
= 1 / 10
220/550 = 0.40
0.40 * 100 = 40%
