Simple calculation: 8 / 15 × 3 / 4-1 / 6 △ 1 / 2 =? 5 / 4 × 5 / 6 + 1 / 6 × 5 / 4 =? 32.6 × 4 / 5 + 32.6 × 20% =?

Simple calculation: 8 / 15 × 3 / 4-1 / 6 △ 1 / 2 =? 5 / 4 × 5 / 6 + 1 / 6 × 5 / 4 =? 32.6 × 4 / 5 + 32.6 × 20% =?

8/15×3/4-1/6÷1/2=2/5-1/6x2=2x(1/5-1/6)=1/15
5/4×5/6+1/6×5/4=5/4×（5/6+1/6）=5/4×1=5/4
32.6×4/5+32.6×20%=32.6X（4/5+1/5)=32.6x1=32.6
