您好,寒樱暖暖为你解答: 你写的9/2表示九分之二吧,一般我们写成2/9 2/9×3/8+3/8+7/9×3/8 =3/8×(2/9+7/9+1) =3/8×2 =3/4 如果你认可我的回答, 请及时点击【采纳为满意回答】按钮,(或在客户端右上角评价点【满意】) 你的采纳, 是我前进...

12+0.375+27/56=12(3/8)+27/56=12(48/56)=12(6/7)

如图

7/8×0.375+3/8÷8/9 =7/8×3/8+3/8×9/8 =(7/8+9/8)×3/8 =2×3/8 =3/4

0.375×14+ 7×37.5%-八分之三的简算 =0.375×(14+7-1) =0.375×20 =7.5

(1)4分之3×30%+5.25×0.3 =0.75×0.3+5.25×0.3 =(0.75+5.25)×0.3 =6×0.3 =1.8 (2)9分之7×37.5%+8分之3×9分之2 =9...

2/9×3/8十0.375十7/9X37.5% =(2/9+1+7/9)×3/8 =2×3/8 =3/4

3/8-0.375×4/7-37.5%×3/7 =0.375-0.375×4/7-0.375×3/7 =0.375×(1-4/7-3/7) =0.375×0 =0

解: 0.375:7/8 =3/8:7/8 =3:7 所以0.375比8分之7化简比是3:7.
