Unit 3 Practice: Complex Fractions

Question 1 (10 points)

A simple fraction contains only digits, comma, and decimal.

True

False

Question 2 (10 points)

Match the print definition to the braille symbol.

1. grade 1 indicator	a. ⠷
2. general fraction open indicator	b. ⠰
3. general fraction close indicator	c. ⠌
4. General fraction line	d. ⠨⠌
5. Simple fraction line	e. ⠾

Question 3 (10 points)

Is this a complex fraction?
$\frac{a}{2}$

True

False

Question 6 (10 points)

Why are there grade 1 indicators before the "c" and the "d" in the following math expression?
$\frac{b^{4} c}{2 d}$

⠰⠷⠃⠰⠔⠼⠙⠰⠉⠨⠌⠼⠃⠰⠙⠾

all letters need a grade 1 indicator after a numeric indicator

the letters "c" and "d" could be misread as 3 and 4

they don't need grade 1 indicators

Question 7 (10 points)

Choose the best braille transcription for:

\frac{2^{a}}{\frac{a}{b} + \frac{c}{d}}
