You need to use the distributive property.

7(1 - 8n)
7 x 1 = 7
7 x -8n = -56n
The equation is -56n + 7

Find the fraction of stundents enrolled in each language

blondinia [14]

Fraction of students enrolled in Chinese = $\frac{51}{126}$

Fraction of students enrolled in French = $\frac{33}{126}$

Fraction of students enrolled in Spanish = $\frac{42}{126}$

Solution:

Total number of students = 51 + 33 + 42

= 126

Number of students enrolled in Chinese = 51

Fraction of students enrolled in Chinese

$$=\frac{\text{Number of students enrolled in Chinese}}{\text{Total number of students}}$

$$=\frac{51}{126}$

Fraction of students enrolled in Chinese = $\frac{51}{126}$

Number of students enrolled in French = 33

Fraction of students enrolled in French

$$=\frac{\text{Number of students enrolled in French}}{\text{Total number of students}}$

$$=\frac{33}{126}$

Fraction of students enrolled in French = $\frac{33}{126}$

Number of students enrolled in Spanish = 42

Fraction of students enrolled in Spanish

$$=\frac{\text{Number of students enrolled in Spanish}}{\text{Total number of students}}$

$$=\frac{42}{126}$

Fraction of students enrolled in Spanish = $\frac{42}{126}$
