解:0.83x9.7+8.3x3等雀亩于( 32951/1000 ),亮岁带【即等于32.951】
∵已知需求出0.83x9.7+8.3x3等于多少
X × Y + X × Z = X × (Y + Z)
∴0.83 x 9.7 + 8.3 x 3
= 0.83 × (9.7 + 3 × 10)
= 83/100 × [(9×10+7)/10 + 30]
= 83/100 × (97/10 + 30)敬芦
= 83/100 × (97/10 + 300/10)
= 83/100 × 397/10
= 32951/1000
= 32.951
答:0.83x9.7+8.3x3等于32951/1000,【即等于32.951】

应历大前该是你的题目写的有问题,但我现在就按你写的来仿返计算肢清。
0.83x9.7+8.3x3
=8.3x0.97+8.3x3 此处给0.83乘以10,给9.7除以10
=8.3x(0.97+3)
=8.3x3.97
=32.951
望采纳,谢谢

解: 0.83x9.7+8.3x3
=0.083x97+8.3x3
=8.3x(0.01X97+3)
=8.3x(0.97+3)
=8.3x0.97+8.3x3
=8.3x(1-0.03)+24.9
=8.3x1-8.3x0.03+24.9
=8.3-0.249+24.9
=8.051+24.9
=32.951
=0.083x97+8.3x3
=8.3x(0.01X97+3)
=8.3x(0.97+3)
=8.3x0.97+8.3x3
=8.3x(1-0.03)+24.9
=8.3x1-8.3x0.03+24.9
