Answer 1

3/4+1/4-3/4-1/4
=（3/4-3/4）+（1/4-1/4）
=0+0
=0

(5/8+2/27)*8+11/27
=5+16/27+11/27
=5+1
=6

36*(7/9+5/6)÷58
=（36x7/9+36x5/6）÷58
=（28+30）÷58
=1

2/3*3/5-1/2÷9/4
=2/5-2/9
=8/45

Answer 2

3/4+1/4-3/4-1/4
=(3/4-3/4)+(1/4-1/4)
=0+0
=0

(5/8+2/27)*8+11/27
=5/8*8+2/27*8+11/27
=5+(16/27+11/27)
=5+1
=6

36*(7/9+5/6)÷58
=(36*7/9+36*5/6)÷58
=(28+30)÷58
=58÷58
=1

2/3*3/5-1/2÷9/4
=2/5-2/9
=18/45-10/45
=8/45
