A. Difference in temperature: 6 degrees.

100(6 / 25) = 24% increase.

B. Difference in temperature: 8 degrees.

100(8 / 32) = 25% increase.

C. Difference in temperature: 9 degrees.

100(9 / 50) = 18% increase.

D. Difference in temperature: 15 degrees.

100(15 / 75) = 20% increase.

25% > 24% > 20% > 18%

Therefore B is the answer.

What is the percent change from 1800 to 1926

Crank

The percentage change is 6.54%
You have to divide 1800÷1926, then multiply by 100 and you'd get 93.46, then subtract 100-93.46 which equals 6.54% :)

Using conversions of mixed numbers, the numbers that are equivalent to 2 and 7/9 are given by:

25/9 and 2.777.

<h3>What are the conversions of the mixed number 2 and 7/9?</h3>

To convert to decimal, we just add the integer part with the fractional part converted to decimal(dividing the numerator by the denominator), hence:

2 and 7/9 = 2 + 7/9 = 2.7777.

To convert to fraction, the procedure is similar, we just apply the least common multiple to add the fraction, as follows:

$2 + \frac{7}{9} = \frac{2 \times 9 + 7}{9} = \frac{25}{9}$
