Answer 1

=4.75*1.36*0.375*4/19*25/34*8/3=136*4.75*0.375*8/(19*34*3)=1.5*4.75*8/(19*3)=4*4.75/19=1

Answer 2

1. 6÷ 3/8 – 3/8 ÷6
=1/6x(3/8-3/8)
=1/6x0
=0

2. 4/7 × 5/9 + 3/7 × 5/9
=(4/7+3/7)x5/9
=1x5/9
=5/9

3. 5/2 -（ 3/2 + 4/5 ）
=5/2-3/2-4/5
=1-4/5
=1/5

4. 6 ×（ 1/2 + 2/3 ）
=6x1/2+6x2/3
=3+4
=7

5. 8 × 4/5 + 8 × 11/5
=8x(4/5+11/5)
=8x3
=24

6. 31 × 5/6 – 5/6
=(31-1)x5/6
=30x5/6
=25

7. 4/5 × 25/16 + 2/3 × 3/4
=5/4+1/2
=5/4+2/4
=7/4

8. 101 × 1/5 – 1/5 × 21
=(101-21)x1/5
=80x1/5
=16
