问题描述:

11分之4×1.375×6 24分之7÷14分之3×1又7分之5

4 / 11 × 1.375 × 6
= 4 / 11 × 11 / 8 × 6
= 4 / 8 × 6
= 1 / 2 × 6
= 3
7 / 24 ÷ 3 / 14 × (1 又 5 / 7)
= 7 / 24 × 14 / 3 × 12 / 7
= 7 / 12 × 7 / 3 × 12 / 7
= 7 × 1 / 3
= 7 / 3

11分之4×1.375×6
=11分之4×8分之11×6
=2分之1×6
=3
24分之7÷14分之3×1又7分之5
=24分之7×3分之14×7分之12
=(24分之7×7分之12)×3分之14
=2分之1×3分之14
=3分之7
=2又3分之1
