Answer 2

Comparing Fractions in Decimal Form

To compare fractions, we can convert them into decimal form and then compare the decimal values. Let's compare the given fractions:

1) 2/11 and 0.182: To convert the fraction 2/11 into a decimal, we divide the numerator (2) by the denominator (11): 2 ÷ 11 = 0.181818... Therefore, 2/11 is approximately equal to 0.182.

2) 2/9 and 77/100: To convert the fraction 2/9 into a decimal, we divide the numerator (2) by the denominator (9): 2 ÷ 9 = 0.222222... Therefore, 2/9 is approximately equal to 0.222.

To convert the fraction 77/100 into a decimal, we divide the numerator (77) by the denominator (100): 77 ÷ 100 = 0.77. Therefore, 77/100 is equal to 0.77.

Comparing the decimal values, we can see that 0.222 is less than 0.77. Therefore, 2/9 is less than 77/100.

3) 11/12 and 19/20: To convert the fraction 11/12 into a decimal, we divide the numerator (11) by the denominator (12): 11 ÷ 12 = 0.916666... Therefore, 11/12 is approximately equal to 0.917.

To convert the fraction 19/20 into a decimal, we divide the numerator (19) by the denominator (20): 19 ÷ 20 = 0.95. Therefore, 19/20 is equal to 0.95.

Comparing the decimal values, we can see that 0.917 is less than 0.95. Therefore, 11/12 is less than 19/20.

4) 47/15 and 19/36: To convert the fraction 47/15 into a decimal, we divide the numerator (47) by the denominator (15): 47 ÷ 15 = 3.133333... Therefore, 47/15 is approximately equal to 3.133.

To convert the fraction 19/36 into a decimal, we divide the numerator (19) by the denominator (36): 19 ÷ 36 = 0.527777... Therefore, 19/36 is approximately equal to 0.528.

Comparing the decimal values, we can see that 3.133 is greater than 0.528. Therefore, 47/15 is greater than 19/36.

In summary: - 2/11 is approximately equal to 0.182. - 2/9 is less than 77/100. - 11/12 is less than 19/20. - 47/15 is greater than 19/36.
