At the candy store, Sophie filled a bag with 2 2/3 kilograms of candy. 1/4 of the weight of the candy was from chocolate covered

Oksana_A [137]

Answer:

The chocolate covered pretzels in Sophie's bag weighed $\frac{2}{3} = 0.6667$ kilograms.

Step-by-step explanation:

Sophie filled a bag with 2 2/3 kilograms of candy.

This means that the total weight is of:

$2\frac{2}{3} = 2 + \frac{2}{3} = \frac{6}{3} + \frac{2}{3} = \frac{8}{3}$

The total weight is of 8/3 kilograms.

1/4 of the weight of the candy was from chocolate covered pretzels. How much did the chocolate covered pretzels in Sophie's bag weigh?

1/4 of 8/3. So

$\frac{1}{4} \times \frac{8}{3} = \frac{1*8}{4*3} = \frac{2}{3} = 0.6667$

The chocolate covered pretzels in Sophie's bag weighed $\frac{2}{3} = 0.6667$ kilograms.

jasenka [17]

Answer:

62.5% increase

Step-by-step explanation:

First step : find the difference between two numbers, in this case, it's 1300000 - 800000 = 500000.

Second Step: Take the difference, 500000, and divide by the original number: 500000/800000 = 0.625.

Last, multiply the number above by 100: 0.625*100 = 62.5%. You're done! You calculated difference of a number in percent, and the answer is a percentage increase of 62.5%.
