Answer 1

Jawab:

a. 2  2/9

b. 4  5/12

Penjelasan dengan langkah-langkah:

a. 3 8/9 - 1 1/6 - 1/2 = 35/9 - 7/6 - 1/2 = 70/18 - 21/18 - 9/18 = 40/18

                             = 2  4/18 = 2  2/9

b. 7 10/12 - 2 1/4 - 1 1/6 = 94/12 - 9/4 - 7/6 = 94/12 - 27/12 - 14/12

                                   = 53/12 = 4  5/12

Answer 2

a. 3 8/9 - 1 1/6 - 1/2

= 35/9 - 7/6 - 1/2

= 140/36 - 42/36 - 18/36

= 98/36 - 18/36

= 80/36

= 80/36 : 4/4 = 20/9

b. 7 10/12 - 2 1/4 - 1 1/6

= 84/12 - 9/4 - 7/6

= 84/12 - 27/12 - 14/12

= 57/12 - 14/12

= 43/12
