First convert the units



1kg=1000g or 1g=1/1000 kg



increase in weight of the pot= 1900g-600g=1300g



%=(change in quantity / original quantity) * 100



%=(1300/600) * 100

=216.67%
Reply:convert to like units:

600g=.6kg



find difference:

1.9kg-.6kg=1.3kg



find porportion of difference to original:

1.3kg/.6kg=2.1666



find percentage by multiplying by 100

2.1666X100=216.66%



i belive only one significatnt figure means you answer would be 200%
Reply:First convert the weight so they are of the same measurement. 1,000 grams = 1 kilogram, so 1.9 kilograms = 1,900 grams. So the weight of the pot increased from 600 grams to 1,900 grams, which is an increase of 1,300 grams. Find the percentage of 1,300 out of 600. First reduce the fraction:



1,300/600 = 13/6

13/6 * 100 = 216 2/3%



Answer: 216 2/3% or about 216.667 % increase
Reply:The empty flower pot weighs 600g and increases 1300g when filled with soil.

If the empty flower pot weighs 100g increases Xg when filled with soil.

x=1300*100/600=216,7%
Reply:The percentage increase

=[(1.9*1000-600)/600]*100%

=2.167*100%

=200% to 1significant figure.
