mohon bantuannya kak!nmor 5,6,7,8,9,10,beserta caranya!

no 9 terserah yah mau ubah satuannya kemana

5. 4/6 +3/6= 7/6
7/6-6/15 =35/30-12/30 = 23/30

6.2 3/4 =11/4
   3 1/2 =7/2
11/4+3/4= 14/4 + 7/2 = 14/4+14/4 =28/4 = 7

7.14,5 /100 = 0,145
8. 1 1/2= 3/2
     0,5= 5/10 = 1/2
     3/2+3/4-1/2 =6/4+3/4-2/4 = 7/4 + 1 3/4

9. 8km = 800000cm
   500 dam=500000cm
800.000+500.000+500=
1.300.500cm

10. 5 ton = 5x1000= 5.000
25kw = 25x100= 2.500
5000+2500= 7500 kg- 3250 kg = 4250 kg

intinya caranya kayak gitu kalo ada yg salah ngitung maaf manusiawi
