Question

3/2-(-5/4)+(-7/5)-(-41/40)=

Answer 1

$\frac{3}{2} -(- \frac{5}{4} )+(- \frac{7}{5} )-(- \frac{41}{40} )= \frac{60}{40} -(- \frac{50}{40} )+(- \frac{56}{40} )-(- \frac{41}{40} )= \\ = \frac{110}{40} +(- \frac{56}{40} )-(- \frac{41}{40} )= \frac{54}{40} -(- \frac{41}{40} )= \frac{95}{40}$
