Fill in the blank with the suitable symbol.
4.23 _____ 4.25 a. I don′t know. b. = c. > d. <

Solution:

4.23 _____ 4.25
[Original statement.]

The ones places of the decimals are the same.

The tenths places of the decimals are the same.

The hundredths place of 4.23 is less than that of 4.25.

Order the fractions $\frac{2}{3}$, $\frac{3}{5}$, and $\frac{5}{6}$ from the greatest to the least . a. $\frac{5}{6}$ < $\frac{2}{3}$ < $\frac{3}{5}$ b. $\frac{5}{6}$ > $\frac{2}{3}$> $\frac{3}{5}$ c. $\frac{3}{5}$ > $\frac{2}{3}$ > $\frac{5}{6}$ d. $\frac{2}{3}$ > $\frac{5}{6}$ > $\frac{3}{5}$

Solution:

The LCD of the fractions is 30.

2 / 3 = 20 / 30 , 3 / 5 = 18 / 30 ,5 / 6 = 25 / 30
[Write the equivalent fractions of the fractions using the LCD as denominator.]

25 / 30 > 20 / 30 > 18 / 30
[Compare the numerators to arrange the fractions in the decreasing order.]

5 / 6 > 2 / 3 > 3 / 5
