Answer:
A 3/5
Step-by-step explanation:Here’s one way to solve this problem.
Write sixty percent as a fraction having a denominator of one hundred.
Now, change sixty-hundredths to an equivalent fraction having a denominator of twenty, the total number of pitches.
Do this by dividing the numerator and the denominator by five.
Then, simplify the fraction twelve-twentieths by dividing the numerator and the denominator by four.
So, Lenora hit three-fifths of the pitches.

Answer:
   23.  x = 4; DE = 44
   24.  x = 25; DS = 28
Step-by-step explanation:
23. Point S is the midpoint of DE, so ...
   DS = SE
   3x +10 = 6x -2
   12 = 3x . . . . . . . . . add 2-3x
   4 = x . . . . . . . . . . . divide by 3
Then DS has length ...
   DS = 3x +10 = 12 +10 = 22
and DE is twice that length, so ...
   DE = 44
__
24. DS is half the length of DE, so is ...
   DS = DE/2 = 56/2
   DS = 28
Then x can be found from ...
   DS = x +3
   28 -3 = x = 25 . . . . . substitute value for DS

<em>Comment on problem 24</em>
Sometimes it is easier to work parts of a problem out of sequence. Here, finding DS first makes finding x easier.
