A. 4 5/20+6 6/20=b. 9 3/15+8 7/45=

Penjelasan dengan langkah-langkah:

bagian a

$4 frac{5}{20} + 6 frac{6}{20} = 10 frac{11}{20}$

bagian b

$9 frac{3}{15} + 8 frac{7}{45} = 9 frac{9}{45} + 8 frac{7}{45} = 17 frac{16}{45}$

A. 4 5/20 + 6 6/20

= 85/20 + 126/20

= 211/20

= 10 11/20

B. 9 3/15 + 8 7/45

= 138/15 + 360/45

= 414/45 + 360/45

= 774/45

= 17 9/45

= 17 1/5
