For the first number, we convert the improper fraction to a mixed number:
0. Divide 18 by 8:
2. The result is 2 with a remainder of 2 which we write as 2/8.
[tex]\frac{18}{8}=2\frac{2}{8}[/tex]
Now, we can simplify this fraction
[tex]\frac{2}{8}=\frac{2\cdot1}{2\cdot4}=\frac{1}{4}[/tex]
Therefore, 18/8 written as a mixed number is:
[tex]$\boldsymbol{\frac{18}{8}=2\frac{1}{4}}$[/tex]
For the second number, we convert the mixed number to an improper fraction:
[tex]1\frac{7}{12}=\frac{12\cdot1+7}{12}=\frac{12+7}{12}=\frac{19}{12}[/tex]
Therefore, 1 7/12 written as an improper fraction is:
[tex]$\boldsymbol{1\frac{7}{12}=\frac{19}{12}}$[/tex]
