a. Berapakah hasil perkalian kedua pecahan tersebut?
b. Berapakah hasil pembagian kedua pecahan tersebut?
tolong ya
Perhatikan dua pecahan berikut: 2 1/3 dan 1 1/2
a. 2 1/3 × 1 1/2
= 7/3 × 3/2
= (7×3)/(3×2)
= 21/6 ÷ 3/3
= 7/2
= 3 1/2
b. 2 1/3 ÷ 1 1/2
= 7/3 ÷ 3/2
= 7/3 × 2/3
= (7×2)/(3×3)
= 14/9
= 1 5/9
Jawaban:
a. 2 1/3×1 1/2
=7/3×3/2
=21/6
=3 3/6
=3 1/2
b. 2 1/3 : 1 1/2
=7/3 : 3/2
=7/3×2/3
=14/9
=1 5/9
semoga membantu
