Penjelasan dengan langkah-langkah:

Jawaban:

4. 6 1/2 + 2 1/3

= ((6×2)+1)/2) + ( (2×3)+1)/3)

= 13/2 + 7/3

=39/6 + 14/6

=. 53/6

= 8 5/6

5.14/3 : 2/3

= 14/3 × 3/2

= 42/6

=7

6. 8 1/3 × 2 1/5

= (8×3)+1 /3 × (2×5)+1/5

= 25/3×11/5

= 275 15

= 18 5/15

= 18 1/3

7. 5 1/5 – 2 1/2

= (5×5)+1/5 – (2×2)+1/2

=26/5 – 5/2

= 52/10 – 25/10

= 27/10

=2 7/10

8. 16 1/2 : 4 1/2 × 6/4

= (33/2 : 9/2) × 6/4

=(33/2 × 2/9) × 6/4

= 66/18 × 6/4

= 396/72

= 5 36/72

= 5 1/2
