解:8.8×8又7/9+11.2×10+1又2/9÷5/44
= (8×10+8)/10 × (8×9+7)/9 + (11×10+2)/10 × 10 + (1×9+2)/9 ÷ 5/44
= 88/10 × 79/9 + 112/10 × 10 + 11/9 ÷ 5/44
= 44/5 × 79/9 + 56/5 × 10 + 11/9 × 44/5
= 3476/45 + 112 + 484/45
= 3476/45 + 5040/45 + 484/45
= 9000/45
= 200
= (8×10+8)/10 × (8×9+7)/9 + (11×10+2)/10 × 10 + (1×9+2)/9 ÷ 5/44
= 88/10 × 79/9 + 112/10 × 10 + 11/9 ÷ 5/44
= 44/5 × 79/9 + 56/5 × 10 + 11/9 × 44/5
= 3476/45 + 112 + 484/45
= 3476/45 + 5040/45 + 484/45
= 9000/45
= 200
