For this case we must subtract the following mixed numbers:
[tex]7 \frac {9} {16} - 4 \frac {2} {4}[/tex]
So:
[tex]7 \frac {9} {16} = \frac {16 * 7 + 9} {16} = \frac {121} {16}\\4 \frac {2} {4} = \frac {4 * 4 + 2} {4} = \frac {18} {4} = \frac {9} {2}[/tex]
We subtract:
[tex]\frac {121} {16} - \frac {9} {2} = \frac {242-144} {32} = \frac {98} {32} = \frac {49} {16}[/tex]
We convert to a mixed number, we have:
[tex]3 \frac {1} {16}[/tex]
Answer:
[tex]3 \frac {1} {16}[/tex]
Option B
