Type of Fractions

Type of Fraction questions

Match the type of fractions.

- Correct!!
- Incorrect! Try again!
- The numerator is smaller than the denominator. \( \frac{1}{6} \)
Feedback: Proper fraction
- The numerator is greater than the denominator. \( \frac{19}{6} \)
Feedback: Improper fraction
- The numerator is the same as the denominator. \( \frac{6}{6} = 1\)
Feedback: Whole fraction
- A whole number and a proper fraction. \( 3\frac {1}{6} \)
Feedback: Mixed fraction

Amplify and simplify fractions

Simplify fraction

Simplify the following fraction:

\( \frac{3}{12} \)

- \( \frac{1}{4} \)
Feedback: Correct! Divide 3 ÷ 3 = 1 and 12 ÷ 3 = 4
- \( \frac{1}{6} \)
Feedback: Incorrect! To simplify you need to divide by the same number. Divide 3 ÷ 3 = 1 and 12 ÷ 3 = 4
- \( \frac{3}{4} \)
Feedback: Incorrect! To simplify you need to divide by the same number. Divide 3 ÷ 3 = 1 and 12 ÷ 3 = 4

Amplify question

Amplify the fraction by 4

\( \frac{4}{6} \)

- \( \frac{4}{24} \)
Feedback: Incorrect!! To amplify you need to multiply the numerator and the denominator by the same number! 4x4 = 16 and 4x6 = 24
- \( \frac{16}{24} \)
Feedback: Correct!! 4x4 = 16 and 4x6 = 24
- \( \frac{8}{9} \)
Feedback: Incorrect!! To amplify you need to multiply the numerator and the denominator by the same number! 4x4 = 16 and 4x6 = 24

Least Common multiple (LCM)

There are different ways to calculate the LCM. You can use any of the methods you fill more comfortable using.

LCM Questions

Find the LCM of 6 and 9

- 18
Feedback: Correct! 6: 6,12,18 9: 9,18
- 12
Feedback: Incorrect! 6: 6,12,18 9: 9,18
- 54
Feedback: Incorrect! 6: 6,12,18 9: 9,18

Addition of fractions

Review the different way you can add fractions, you can write examples on your math notebook.

In the video you can see an example of how to add fractions with different denominators.

Addition question (same denominator

Solve the addition operation

\( \frac{8}{9} + \frac{4}{9} \)

- \( \frac{12}{9} \)
Feedback: Correct! 8+4= 12 and the denominator stays the same = 9
- \( \frac{12}{18} \)
Feedback: Incorrect! 8+4= 12 and the denominator stays the same = 9
- \( \frac{4}{9} \)
Feedback: Incorrect! 8+4= 12 and the denominator stays the same = 9

Subtraction of fraction question

Solve the subtraction operation using the LCM.

\( \frac{10}{4} - \frac{9}{12} \)

- \( \frac{21}{12} \)
Feedback: Correct!! LCM = 12 Incorrect!! LCM = 12 \( \frac{10}{4} \) x 3 = \(\frac{30}{12} - \frac{9}{12} \)
- \( \frac{1}{12} \)
Feedback: Incorrect!! LCM = 12 \( \frac{10}{4} \) x 3 = \(\frac{30}{12} - \frac{9}{12} \)
- \( \frac{19}{12} \)
Feedback: Incorrect!! LCM = 12 Incorrect!! LCM = 12 \( \frac{10}{4} \) x 3 = \(\frac{30}{12} - \frac{9}{12} \)
