Question 1.
Which of the following statements is correct?
(A) The product of \(\frac{3}{4}\) and \(\frac{7}{8}\) is less than \(\frac{7}{8}\).
(B) The product of 1\(\frac{1}{3}\) and \(\frac{9}{10}\) is less than \(\frac{9}{10}\).
(C) The product of \(\frac{3}{4}\) and \(\frac{7}{8}\) is greater than \(\frac{7}{8}\).
(D) The product of \(\frac{7}{8}\) and \(\frac{9}{10}\) is greater than \(\frac{9}{10}\).
Answer:
(A) The product of \(\frac{3}{4}\) and \(\frac{7}{8}\) is less than \(\frac{7}{8}\).
Explaination:
The correct answer is A. Really:
\(\frac{3}{4} \times \frac{7}{8}\) = \(\frac{3 \times 7}{4 \times 8}\)
= \(\frac{21}{32}\)
And
\(\frac{7}{8}\) = \(\frac{7 \times 4}{8 \times 4}\)
= \(\frac{28}{32}\)
We can notice that:
\(\frac{3}{4} \times \frac{7}{8}=\frac{21}{32}<\frac{28}{32}=\frac{7}{8}\)
Question 2.
Which shows the GCF of 18 and 24 with \(\frac{18}{24}\) in simplest form?
(A) GCF: 3; \(\frac{3}{4}\)
(B) GCF: 3; \(\frac{6}{8}\)
(C) GCF: 6; \(\frac{3}{4}\)
(D) GCF: 6; \(\frac{6}{8}\)
Answer:
(C) GCF: 6; \(\frac{3}{4}\)
Explaination:
GCF for 48 and 24 is 6, so, we have the following form of this fraction:
\(\frac{18}{24}=\frac{18 \div 6}{24 \div 6}=\frac{3}{4}\)
Conclusion is that correct answer is C.
Question 3.
A jar contains 133 pennies. A bigger jar contains 1\(\frac{2}{7}\) times as many pennies. What is the value of the pennies in the bigger jar?
(A) $ 1.49
(B) $ 1.52
(C) $ 1.68
(D) $ 1.71
Answer:
(D) $ 1.71
Explaination:
The value of pennies in the bigger jar is product of 133 and 1\(\frac{2}{7}\), so we have the following:
So, the value of pennies in the bigger jar is 171.
Conclusion is that correct answer is D.
Question 4.
Which of these is the same as \(\frac{3}{5}\) ÷ \(\frac{4}{7}\)?
(A) \(\frac{3}{5} \div \frac{7}{4}\)
(B) \(\frac{4}{7} \div \frac{3}{5}\)
(C) \(\frac{3}{5} \times \frac{4}{7}\)
(D) \(\frac{3}{5} \times \frac{7}{4}\)
Answer:
(D) \(\frac{3}{5} \times \frac{7}{4}\)
Explaination:
The first step at dividing two factors is to rewrite the problem as multiplication
Using the reciprocal of the second fraction.
Here, reciprocal of \(\frac{4}{7}\) is \(\frac{7}{4}\) and equivalent is expression \(\frac{3}{5} \times \frac{7}{4}\)
Conclusion is that correct answer is D.
Question 5.
What is the reciprocal of 3\(\frac{3}{7}\)?
(A) \(\frac{7}{24}\)
(B) \(\frac{3}{7}\)
(C) \(\frac{7}{3}\)
(D) \(\frac{24}{7}\)
Answer:
(A) \(\frac{7}{24}\)
Explaination:
First we will find mixed number as a fraction greater than 1:
3\(\frac{3}{7}\) = \(\frac{24}{7}\)
The reciprocal of \(\frac{24}{7}\) is \(\frac{7}{24}\). So, conclusion is that correct answer is A.
Question 6.
A rectangular patio has a length of 12\(\frac{1}{2}\) feet and an area of 103\(\frac{1}{8}\) square feet. What is the width of the patio?
(A) 4\(\frac{1}{8}\) feet
(B) 8\(\frac{1}{4}\) feet
(C) 16\(\frac{1}{2}\) feet
(D) 33 feet
Answer:
(B) 8\(\frac{1}{4}\) feet
Explaination:
The width of the patio we will dividing the area of patio, 103\(\frac{1}{8}\), by its length, 12\(\frac{1}{2}\)
So, we have the following:
So, the width of the patio is 8\(\frac{1}{4}\) feet. Correct answer is B.
Gridded Response
Question 7.
Jodi is cutting out pieces of paper that measure 8\(\frac{1}{2}\) inches by 11 inches from a large sheet that has an area of 1,000 square inches. What is the area of each piece of paper that Jodi is cutting out written as a decimal?
Answer:
The area of each piece of paper is product of 8\(\frac{1}{2}\) and 11:
8\(\frac{1}{2}\) × 11 = \(\frac{17}{2} \times \frac{11}{1}\)
= \(\frac{17 \times 11}{2}\)
= \(\frac{187}{2}\)
= 93.5
So, the area of each piece of paper that Jodi is cutting out is 93.5 square inches.
