Answer 2

Answer 3

原式
=-4-7/8+5+1/2-4-1/4-3-1/8
=-4+5-4-3-7/8+1/2-1/4-1/8
=-6+2/4-1/4-(7/8+1/8)
=-7+1/4
=-(6又3/4)

Answer 4

(－4又7/8)－(－5又1/2)+(－4又1/4)－(+3又1/8)
=－39/8+11/2－17/4－25/8
=(－39－25)/8+(22－17)/4
=－64/8+5/4
=－8+0.8
=－7.2

Answer 5

-4-7/8+5+1/2-4-1/4-3-1/8
=1-1-4+1/2-1/4-3
=-7+1/4
=-6-4/4+1/4
=-6-3/4
=-6又3/4
