Answer 1

Answer:

\frac{23}{15}  = 1.5

Step-by-step explanation:

\frac{3}{4}  +  \frac{1}{2}  \times  2\frac{1}{2}  -  \frac{2}{3}  \times \frac{7}{8}   \div  \frac{5}{4}  \\  =  \frac{3}{4}  +  \frac{1}{2}  \times  \frac{5}{2}  -  \frac{14}{24}  \times  \frac{4}{5}  \\   =  \frac{3}{4}  +  \frac{5}{4}  -  \frac{56}{120}  \\  =  \frac{90 + 150 - 56}{120}  \\  =  \frac{184}{120}   \\  =  \frac{23}{15}  \\  = 1.5
