Example Question #381 : Number & Operations With Fractions

Fill in the blank with the correct symbol. 

\(\displaystyle \frac{2}{4}\) __________ \(\displaystyle \frac{2}{10}\)

 

Possible Answers:

\(\displaystyle >\)

\(\displaystyle =\)

\(\displaystyle < \)

Correct answer:

\(\displaystyle >\)

Explanation:

\(\displaystyle \frac{2}{4}>\frac{2}{10}\)

If you look at the images, both circles have \(\displaystyle 2\) shaded regions; however, the circle that was divided into \(\displaystyle 4\) parts has bigger shaded regions than the circle that was divided into \(\displaystyle 10\) parts.

Using this information, you can see that the circle divided into \(\displaystyle 4\) parts possesses a larger shaded region; therefore,

 \(\displaystyle \frac{2}{4}>\frac{2}{10}\)

2 42 10

Possible Answers:

\(\displaystyle =\)

\(\displaystyle < \)

\(\displaystyle >\)

Correct answer:

\(\displaystyle < \)

Explanation:

\(\displaystyle \frac{3}{12}< \frac{3}{8}\)

If you look at the images, both circles have \(\displaystyle 3\) shaded regions; however, the circle that was divided into \(\displaystyle 12\) parts has smaller shaded regions than the circle that was divided into \(\displaystyle 8\) parts.

Using this information, you can see that the circle divided into \(\displaystyle 12\) parts possesses a smaller shaded region; therefore,

 \(\displaystyle \frac{3}{12}< \frac{3}{8}\)

Example Question #383 : Understanding Fractions As Numbers

Fill in the blank with the correct symbol. 

\(\displaystyle \frac{5}{6}\) __________ \(\displaystyle \frac{5}{12}\)

 

Possible Answers:

\(\displaystyle >\)

\(\displaystyle < \)

\(\displaystyle =\)

Correct answer:

\(\displaystyle >\)

Explanation:

\(\displaystyle \frac{5}{6}>\frac{5}{12}\)

If you look at the images, both circles have \(\displaystyle 5\) shaded regions; however, the circle that was divided into \(\displaystyle 6\) parts has bigger shaded regions than the circle that was divided into \(\displaystyle 12\) parts.

Using this information, you can see that the circle divided into \(\displaystyle 6\) parts possesses a larger shaded region; therefore,

 \(\displaystyle \frac{5}{6}>\frac{5}{12}\)

5 65 12

Example Question #384 : Understanding Fractions As Numbers

Correct answer:

\(\displaystyle < \)

Explanation:

\(\displaystyle \frac{4}{8}< \frac{4}{5}\)

If you look at the images, both circles have \(\displaystyle 4\) shaded regions; however, the circle that was divided into \(\displaystyle 8\) parts has smaller shaded regions than the circle that was divided into \(\displaystyle 5\) parts.

Using this information, you can see that the circle divided into \(\displaystyle 8\) parts possesses a smaller shaded region; therefore,

 \(\displaystyle \frac{4}{8}< \frac{4}{5}\)

4 84 5

Example Question #385 : Understanding Fractions As Numbers

\(\displaystyle \frac{1}{6}\) __________ \(\displaystyle \frac{1}{10}\)

 

Possible Answers:

\(\displaystyle < \)

\(\displaystyle >\)

\(\displaystyle =\)

Correct answer:

\(\displaystyle >\)

Explanation:

\(\displaystyle \frac{1}{6}>\frac{1}{10}\)

If you look at the images, both circles have \(\displaystyle 1\) shaded region; however, the circle that was divided into \(\displaystyle 6\) parts has bigger shaded regions than the circle that was divided into \(\displaystyle 10\) parts.

Using this information, you can see that the circle divided into \(\displaystyle 6\) parts possesses a larger shaded region; therefore,

 \(\displaystyle \frac{1}{6}>\frac{1}{10}\)

1 61 10
