Jawaban:

1. D 1/2

2. 2 9/40

Penjelasan dengan langkah-langkah:

3/6 + 1/4 + 2/3 – 11/12

=6/12 + 3/12 + 8/12 – 11/12

=17/12 – 11/12

=6/12

=1/2

1 3/8 + 4 6/10 – 3 3/4

=1+4–3 +(3/8 + 6/10 – 3/4)

=2 +(15/40 + 24/40 – 30/40)

=2 (39/40 – 30/40)

=2 9/40

3/6 + 1/4 + 2/3 – 11/12

6/12 + 3/12 + 8/12 – 11/12 = 17/12 – 11/12 = 6/12 = 1/2

1 3/8 + 4 6/10 – 3 3/4

11/8 + 46/10 – 15/4

55/40 + 184/40 – 150/40 = 89/40 = 2 9/40
