tolong jawab no 6-10,11-14

No 6.
[tex] \frac{13}{12} [/tex]

6. 3/4 + 2/6
3/4 x 3 = 9/12
2/6 x 2 = 4/12
9/12 + 4/12 = 13/12
7. 4/6 + 1/2
4/6 x 1 = 4/6
1/2 x 3 = 3/6
4/6 + 3/6 = 7/6
8. 2/5 + 2/4
2/5 x 4 = 8/20
2/4 x 5 = 10/20
8/20 + 10/20 = 18/20
18/20 : 2 = 9/10
9. 1/2 + 1/4
1/2 x 2 = 2/4
1/4 x 1 = 1/4
2/4 + 1/4 = 3/4
10. 2/5 + 1/4
2/5 x 4 = 8/20
1/4 x 5 = 5/20
8/20 + 5/20 = 13/20
11. 2/4 + 40%
2/4 + 40/100
2/4 x 25 = 50/100
40/100 x 1 = 40/100
50/100 + 40/100 = 90/200
90/200 : 2 = 45/100 = 45%
12. 50% + 0,2
50/100 + 2/10
50/100 x 1 = 50/100
2/10 x 10 = 20/100
50/100 + 20/100 = 70/200
70/200 : 2 = 35/100 =35%
13. 45% + 0,45
45/100 + 45/100 = 90/200
90/200 : 2 = 45/100 = 45%
