6/8 divide by 8/12 A. 9/2 B. 8/9 C. 9/8 D. 9/32

Musya8 [376]

Answer:

C. 9/8

Step-by-step explanation:

$\frac{6}{8} \div \frac{8}{12}$

Use KCF which means Keep the first fraction, Change the second fraction by flipping it and change the division sign to a multiplication symbol:

$\frac{6}{8} \times \frac{12}{8}$

multiply the numerator together:

6 × 12 = 72

multiply the denominator together:

8 × 8 = 64

now the fraction is:

$\frac{72}{64}$

simplify further by dividing both numbers by 8:

72 ÷ 8 = 9

64 ÷ 8 = 8

so the fraction is 9/8

Among 500 freshmen pursuing a business degree at a university, 311 are enrolled in an economics course, 243 are enrolled in a ma

Allushta [10]

Solution :

Let A = Economics, B = Mathematics

n(A) = 311, n(B) = 243, $n(A \cap B) = 135$

a). So, $n(A \cup B) = n(A) +n(B) - n(A \cap B)$

= 311 + 243 - 135

= 419

b). n(A only) = 311 - 135

= 176

n(B only) = 243 - 135

= 108

Exactly one of these two courses

$=\frac{176+108}{500}$

= 0.568

c). Neither economics nor mathematics

$=\frac{500-419}{500}$

$=\frac{81}{500}$

= 0.162
