please give the answer with full explanation ​

Answer 1

Step-by-step explanation:

= -1+(-3/8)+1/2-7/4

= -1+(-3/8)+1/2-7/4= -1-3/8+1/2-7/4

= -1+(-3/8)+1/2-7/4= -1-3/8+1/2-7/4= (1/2)-(1+3/8+7/4)

= -1+(-3/8)+1/2-7/4= -1-3/8+1/2-7/4= (1/2)-(1+3/8+7/4)= (1/2) -(25/8)

= -1+(-3/8)+1/2-7/4= -1-3/8+1/2-7/4= (1/2)-(1+3/8+7/4)= (1/2) -(25/8) = 1/2-25/8

= -21/8

= (1/2)
