4 2/5=22/5
41/5-22/5= 19/5=3 4/5
Answer: 3 4/5
For this case we must find the value of the following expression:
[tex]8 \frac {1} {5} -4 \frac {2} {5}[/tex]
We have to:
[tex]8 \frac {1} {5} = \frac {5 * 8 + 1} {5} = \frac {40 + 1} {5} = \frac {41} {5}\\4 \frac {2} {5} = \frac {5 * 4 + 2} {5} = \frac {20 + 2} {5} = \frac {22} {5}[/tex]
Subtracting we have:
[tex]\frac {41} {5} - \frac {22} {5} = \frac {19} {5}[/tex]
In mixed number it is equivalent to:
[tex]3 \frac {4} {5}[/tex]
ANswer:
[tex]3 \frac {4} {5}[/tex]
