Jawab:

-23/3

Penjelasan dengan langkah-langkah :

1 1/3 – 3 3/4 × 2 2/5

= ((1×3)/3 + 1/3) – ((3×4)/4 + 3/4) x ((2×5)/5 + 2/5)

= (3/3 + 1/3) – (12/4 + 3/4) x (10/5 + 2/5)

= 4/3 – 15/4 × 12/5

= 4/3 – (15:5)/(4:4) x (12:4)/(5:5)

= 4/3 – 3/1 × 3/1

= 4/3 – 9/1

= 4/3 – (9×3)/(1×3)

= 4/3 – 27/3

= -23/3
