解:4/9×3/8+3/4÷(9/16)等于( 3/2 ),【即等于1.5】
∵已知需求出4/9×3/8+3/4÷(9/16)等于多少
∴4/9 × 3/8 + 3/4 ÷ (9/16)
= 4/(3×3)× 3/(4×2)+ 3/4 × 16/9
= 1/6 + 3/4 × (4×4)/(3×3)
= 1/6 + 4/3
= 1/6 + (4×2)/(3×2)
= 1/6 + 8/6
= 9/6
= 3/2
= 1.5
答:4/9×3/8+3/4÷(9/16)等于3/2,【即等于1.5】
4/9×3/8+3/4÷(9/16)
=4/9×3/8+3/4x16/9
=1/6+4/3
=1/6+8/6
=9/6
=3/2
4/9×3/8+3/4÷(9/16)
=1/6+3/4×16/9
=1/6+4/3
=1/6+8/6
=9/6
=3/2
