Question 1

Show that the number is a rational number by finding a ratio of two integers equal to the number. $4 \frac { 2 } { 5 }$
A) $\frac { 13 } { 5 }$
B) $\frac { 22 } { 5 }$
C) $\frac { 6 } { 5 }$
D) $\frac { 8 } { 5 }$

Accepted Answer

To convert the mixed number $4 \frac{2}{5}$ to an improper fraction, multiply the whole number (4) by the denominator (5) and add the numerator (2), which gives $4*5 + 2 = 20 + 2 = 22$. Thus, the fraction is $\frac{22}{5}$.

Question 2

Fill in the blank with the appropriate symbol: <, >, or =. $\frac{53}{26}$________$\frac{56}{27}$ A) > B) = C) <

Accepted Answer

To compare $\frac{53}{26}$ and $\frac{56}{27}$, it's helpful to simplify or compare their decimal forms. $\frac{53}{26} = 2.038...$ and $\frac{56}{27} = 2.074...$. Since 2.038 is less than 2.074, $\frac{53}{26} < \frac{56}{27}$.

A) $\frac { 1 } { 6 }$
B) $\frac { 6 } { 0 }$
C) $\frac { 0 } { 6 }$
D) $\frac { 6 } { 1 }$

Accepted Answer

A rational number is defined as a number that can be expressed as the quotient or fraction of two integers, a numerator and a denominator, with the denominator not equal to zero. The number 6 can be expressed as $\frac{6}{1}$, which fits this definition.
