She walked the most on Friday because you have to find the LCD. The LCD is 24.
For example, to change the denominator of 4 to 24, you must divide 24 divided by 4 which equals 6. Since your answer was 6, you have to multiply both numbers, which are 3 and 4, by 6.
So, 4 times 6 is 24. This is the denominator and 4 times 3 is 18. This is the numerator.
If you do the same with all of the fractions then you will have the fractions of, 18 over 24, 12 over 24, and 9 over 24.
Look at all the numerators (the number on top of the fraction) and decide which one is the biggest.
18 is the biggest and since the fraction 18 over 24 was originally 3 over 4, this means that she walked the most on Friday.
Hoped this helps!!

Hello!
We can use the special binomial product formulas:
<h3>Simplify</h3>
The simplified form is 
C
there can be more than one mode. 20 and 30 have the same amount and are most frequent
Answer:The formula for a combination of choosing r unique ways from n possibilities is:
nCr = n!
r!(n - r)!
where n is the number of items and r is the unique arrangements.
Plugging in our numbers of n = 10 and r = 0, we get
10C0 = 10!
0!(10 - 0)!
10C0 = 3,628,800
3,628,800
Answers:
Row one: 1 and 1
Row two: 1, 2, and 1
Row three: 1, 3, 3, and 1
Row four: 1, 4, 6, 4, and 1
=========================================
Explanation:
Each value can be found in Pascal's triangle. You can also use the nCr combination formula to get each value. The nCr formula is

The value of n represents the row number. The r value is the column number, so to speak, for each row.
