= 4/7 × 5/6 + 1 2/3
= (4 × 5)/(7 × 6) + 5/3
= 20/42 + 5/3
= 10/21 + 5/3
= 10/21 + 35/21
= (10 + 35)/21
= 45/21
= 2 3/21
= 2 1/7 ( A )
Jawaban:
A. 2⅐
Penjelasan dengan langkah-langkah:
4/7 x 5/6 + 1⅔ = 4 x 5 + 5/3
7 x 6
= 20 / 42 + 5/3. ( 20/42 sama sama dibagi 2)
= 10/21 + 5 x 7
3 x 7
= 45/21. (sama sama bagi 3)
= 15/ 7
= 2⅐
