2/15 – 1/2 + 3/10 = ……….

2/15-1/2+3/10=…
4-15+9 per 30= min 11+9 per 30
= min 2 per 30 = min 1 per 15

1. 7/10 – 4/15 =
2. 2/3 + 1/4 – 1/2 =
3. 3/5 + 1/4 – 1/2 =
4. 2/5 + 3/10 – 2/15 =

Jawaban:

1.13/30

2. 5/12

3. 7/20

4. 17/30

Penjelasan dgn tindakan:

1. 7/10 – 4/15 = 21-8/30 = 13/30

2. 2/3 + 1/4 – 1/2 = 8+3-6/12=5/12

3. 3/5 + 1/4 – 1/2 =12+5-10/20=7/20

4. 2/5 + 3/10 – 2/15 = 12+9-4/30=17/30

2/15 – 1/2 + 3/10 =

2 per 15 – 1 per 2 + 3 per 10 =

2/15 – 1/2 + 3/10
(4/30 – 15/30) + 9/30
-11/30 + 9/30
-2/30

2/15 – 1/2 + 3/10 =

(2 per 15 – 1 per 2 + 3 per 10)

-2/30
