therefore 9 successful attempts.

Question 6.
Write the ratio 7 to 8 as a fraction, decimal, and percent,
fraction: _____ decimal: _______ percent: ______
Fraction : $$\frac{7}{8}$$,
Decimal : 0.875,
Percent : 87.5%,

Explanation:
Given the ratio 7 to 8 as a fraction, decimal, and percent,
So fraction will be $$\frac{7}{8}$$, Decimal is when
7 is divided by 8 we get 0.875 and percentage is calculated
with 100 so percent is 0.875 X 100 = 87.5%.

Question 7.
On a history test, Robert gets 23 questions correct out of 25. What is Robert’s percent score for the test? Show how you know.
________________
92%,

Explanation:
Given on a history test, Robert gets 23 questions correct out of 25.
Therefore Robert’s percent score for the test is as we calculate
percentage for 100 so it is $$\frac{23}{25}$$ X 100 =
23 X 4 = 92%,  therefore Robert’s percent score for the test is 92%.

Question 8.
Write the following ratios in order from least to greatest: 82%, $$\frac{16}{20}$$, 35 out of 40.
________________
$$\frac{16}{20}$$, 82%, 35 out of 40,

Explanation:
Given to write the following ratios in order from least to greatest:
82%, $$\frac{16}{20}$$, 35 out of 40, as
$$\frac{16}{20}$$ = 0.8 and 35 out of 40 =
$$\frac{35}{40}$$ X 100 = 87.5% therefore
the ratios in order from least to greatest:
$$\frac{16}{20}$$, 82%, 35 out of 40.

Question 9.
