Jawab:

Penjelasan dengan langkah-langkah:

1. a. 1/2 + 3

= 1/2 + 6/2

= 7/2

b. 6 3/7 - 3

= 45/7 - 21/7

= 24/7

2. cat 4 kg dikurangi cat lemari 1,02 kg = 2,98 kg

dikurangi 4/5 kg untuk cat meja = 2, 98 kg - 4/5 kg

=2 98/100 - 80/100

=2 18/100 = 2, 18 kg

3. a. 4/5 : 2 1/3

= 4/5 : 7/3

=4/5 x 3/7

=12/35

b. 5 x 2 5/3

= 5 x 11/3

= 55/3 = 18 1/3

c. 5/8 x 48% x 2 4/9

= 5/8 x 48/100 x 22/ 9

= 5280/ 7200 = 528/720 = 44/60
