Haruka hiked several kilometers in the morning. She only hiked 6 kilometers in the afternoon, which was 25 percent less she had
2 answers:
Answer:
14 kilometers.
Step-by-step explanation:
Let x be the kilometers she hiked on morning,
25% of the hiked kilometers on morning = 25% of x
= 0.25x
Thus, 25% less of the hiked kilometers on morning = x - 0.25x
= 0.75x
According to the question,
0.75x = 6
Thus, she hiked 8 km in morning,
And, the total kilometers she hiked = hiked kilometers on morning + hiked kilometers on afternoon
= 8 + 6
= 14

Converting the mixed number to a decimal, the correct comparison of the numbers is given as follows:
A mixed number is represented by an integer part and a fractional part, as follows:
a b/c.
In which:
- a is the integer part.
- b/c is the fractional part.
In this problem, the numbers are given as follows:
The mixed number is:
100 and 2/8 = 100 + 0.25 = 100.25.
The square root is an increasing function, hence the higher the input, the higher the square root, as 180 > 100 the comparison is:
