lisa123 one year ago what will be the amount of sugar in milligrams if the size of the milk chocolate bar is reduced from 17.00g to 5.00g

1. calculusxy

First we should convert the grams into mg... 1 gram = 1000 mg 17 g = 17,000mg 5 g = 5,000mg

2. calculusxy

And then you can subtract 17,000mg - 5,000mg

@lisa123

5. lisa123

12,000mg??

6. calculusxy

yes!

7. calculusxy

oh wait....

8. calculusxy

if it is just saying to know in mg after it got reduced to 5g, then it is only 5000mg

9. lisa123

no thats not the right answer

10. lisa123

originally there is 17g of milk and 10.5g of sugar in the milk

11. phi

do they tell how much sugar is in the larger bar ?

12. calculusxy

then i think that you can make a proportion

13. lisa123

thats what i thought idk how to do it

14. lisa123

@calculusxy @phi

15. phi

$\frac{5}{17} = \frac{x}{10500}$

16. lisa123

17x/5(10500)??

17. lisa123

x=2.948

18. lisa123

294.1

19. phi

I would multiply both sides by 10500 $\frac{5}{17}\cdot 10500 = \frac{x}{10500}\cdot 10500$

20. phi

on the right side , 10500/10500 simplifies to 1 and 1*x is x the left side will be the answer in milligrams

21. lisa123

Thank you!

22. phi

what did you get ?

23. lisa123

3088mg

24. phi

yes, that looks good.
