Marcus is 5 19/24 feet tall. Ben is 5 9/16 feet tall. Which of the two boys is taller?
Ksju [112]

well, Marcus and Ben are both 5 feet tall and a little bit more, Marcus is 19/24 more and Ben is 9/16 more, so the 5's in the fraction are the same, so which one is larger, 19/24 or 9/16?

we can simply put both fractions with the same denominator, by <u>multiplying one by the other's denominator</u>, so let's proceed,

\bf \stackrel{\textit{\large Marcus is taller}}{5~feet + \left( \cfrac{19}{24}\cdot \cfrac{16}{16}\implies \boxed{\cfrac{304}{384}} \right)}\qquad \qquad \qquad \stackrel{\textit{\large Ben}}{5~feet + \left( \cfrac{9}{16}\cdot \cfrac{24}{24}\implies \boxed{\cfrac{216}{384}} \right)}

Which expression completes the statement to form a true inequality?
Alexeev081 [22]

we are supposed to find

The expression that completes the statement to form a true inequality

3+6^2

Here 3+6^2=3+36=39\\

So the given inequality to be true the value of the option(s) should me bore than 39

First option: 3^3 + 12=27+12=39

As its not more than 39. Hence its not the correct option.

Second Option : 5^2 + 4^2=25+16=41\\

Hence this is the correct option so,

3+6^2

Third Option: 2^3 + 5^2 + 6=8+25+6=39\\

As its not more than 39. Hence its not the correct option.

Fourth Option: 2^3 + 14 +17=8+ 14 +17=39\\

As its not more than 39. Hence its not the correct option.
