For this case we must simplify the following expression:
[tex]\frac {\frac {7} {8} + (- \frac {2} {3})} {\frac {5} {6}} =[/tex]
We know that: [tex]+ * - = -[/tex]
So:
[tex]\frac {\frac {7} {8} - \frac {2} {3}} {\frac {5} {6}} =[/tex]
We solve the subtraction of the numerator:
[tex]\frac {\frac {3 * 7-8 * 2} {8 * 3}} {\frac {5} {6}} =\\\frac {\frac {21-16} {24}} {\frac {5} {6}} =\\\frac {\frac {5} {24}} {\frac {5} {6}} =[/tex]
Applying double c:
[tex]\frac {5 * 6} {24 * 5} =\\\frac {30} {120} =\\\frac {1} {4}[/tex]
Answer:
[tex]\frac {1} {4}[/tex]
