what will 7.89kg be if it is expressed in kilogram and gram?a.7kg830gb.7kg83gc.78kg30gd.78kg3gSince 1kg = 1000g, therefore, 0.89g = 890g~So, the answer is A

1. 135x80% = 108
2. (238x100%)÷280 = 238÷280 = 0.85
3. (50-5x5)÷50 = (50-25)÷50 = 25÷50 = 0.5
4. 300-150x75% = 300-112.5 = 187.5
5. 425-28x23 = 425-644 = -219
6. b
7. Where is the picture?
8. a
10. a

I hope I can help you. ^_^
