Question

order each set of numbers from least to greatest. (example 4 )

1. {0.23, 19\\%, $\frac{1}{5}$}
2. {$ - 0.615, - \frac{5}{8}, - 0.62 $}
3. liberty middle school is holding a fundraiser. the sixth - graders have raised 52\\% of their goal amount. the seventh - and eighth - graders have raised 0.57 and $\frac{2}{5}$ of their goal amounts, respectively. list the classes in order from least to greatest of their goal amounts. (example 5)

fill in each $\bigcirc$ with $<$, $>$, or $=$ to make a true sentence.
9 $1 \frac{7}{12}$ gallons $\bigcirc$ $1 \frac{5}{8}$ gallons

1. $2 \frac{5}{6}$ hours $\bigcirc$ 2.8 hours

Explanation:

Problem 6:

Step1: Convert to decimals

19% = 0.19, \(\frac{1}{5}\) = 0.2.

Step2: Order decimals

0.19 < 0.2 < 0.23.

Step1: Convert fraction to decimal

\(-\frac{5}{8}\) = -0.625.

Step2: Order decimals (negative)

-0.625 < -0.62 < -0.615.

Step1: Convert to decimals

52% = 0.52, \(\frac{2}{5}\) = 0.4.

Step2: Order decimals

0.4 < 0.52 < 0.57.

Step3: Map to classes

\(\frac{2}{5}\) (eighth - graders), 52% (sixth - graders), 0.57 (seventh - graders).

Answer:

19%, \(\frac{1}{5}\), 0.23
