tolong kk tunjukan jawaban nya

1.7+8+100=c.115
2.9-4+5=b.10
3.20+4500+12=c.4532
4.250+400+35000=b.35650

1. 7 + 8 + 100 = 115 (c)

2. 9 - 4 + 5 = 10 (b)

3. 2 dam = 20 m
45 hm = 4.500 m
120 dm = 12 m
= 20 m + 4.500 m + 12 m
= 4.532 m (c)

4. 250 gram = 250 gram
4 ons = 400 gram
35 kg = 35.000 gram
= 250 + 400 + 35.000
35.650 gram (b)
