解:36.8乘以1.5再加上二分之十七乘以36.8等于( 368 )
∵已知需求出36.8乘以1.5再加上二分之十七乘以36.8等于多少
A × B + A × C = A × (B + C)
∴36.8乘以1.5再加上二分之十七乘以36.8
= 36.8 × 1.5 + 17/2 × 36.8
= 36.8 × (1.5 + 17/2)
= (36×10+8)/10 × [(1×10+5)/10 + 17/2]
= 368/10 × (15/10 + 17/2)
= 184/5 × (3/2 + 17/2)
= 184/5 × 20/2
= 184/5 × 10
= 368
答:36.8乘以1.5再加上二分之十七乘以36.8等于368
∵已知需求出36.8乘以1.5再加上二分之十七乘以36.8等于多少

= 368/10 × (15/10 + 17/2)
= 184/5 × (3/2 + 17/2)
= 184/5 × 20/2
= 184/5 × 10
= 368
答:36.8乘以1.5再加上二分之十七乘以36.8等于368
