Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. which of the following shows \\(\frac{18}{8}\\) as a mixed number and \\(1\frac{7}{12}\\) as an improper fraction? \\(\frac{18}{8} = 1\frac{5}{4}\\) and \\(1\frac{7}{12} = 1\frac{12}{7}\\) \\(\frac{18}{8} = 2\frac{1}{4}\\) and \\(1\frac{7}{12} = \frac{19}{12}\\) \\(\frac{18}{8} = 2\frac{2}{8}\\) and \\(1\frac{7}{12} = \frac{8}{12}\\) \\(\frac{18}{8} = \frac{9}{4}\\) and \\(1\frac{7}{12} = \frac{17}{12}\\)

Explanation:

Step1: Convert $\frac{18}{8}$ to mixed number

Divide 18 by 8: $18 = 8\times2 + 2$, so $\frac{18}{8}=2\frac{2}{8}=2\frac{1}{4}$

Step2: Convert $1\frac{7}{12}$ to improper fraction

Use formula $a\frac{b}{c}=\frac{a\times c + b}{c}$: $\frac{1\times12 + 7}{12}=\frac{19}{12}$

Answer:

$\boldsymbol{\frac{18}{8}=2\frac{1}{4}}$ and $\boldsymbol{1\frac{7}{12}=\frac{19}{12}}$ (the second option)
