Question

Suppose a class has 14 redheads, 8 brunettes, and 6 blondes a. What is the ratio of redheads to brunettes? b. What is the ratio of redheads to blondes? c. What is the ratio of blondes to brunettes? d. What is ratio of blondes to total students?

Answer 1

a) 14/8 = 7 : 4

b) 14/6 = 7 : 3

c) 8/6 = 4 : 3

d) Total students = 14+8+6

= 28

28/6 = 14 : 3

Answer 2

Answer:

a. The ratio of redheads to brunettes = 7: 4

b. The ratio of redheads to blondes = 7: 3

c. The ratio of blondes to brunettes = 3: 4

d. The ratio of blondes to total students = 3: 14

Step-by-step explanation:

The number of redhead students R = 14

The number of brunettes Br = 8

The number of blondes Bl = 6

Total number of students T = 14 + 8 + 6 = 28

a. The ratio of redheads to brunettes is

$\frac{R}{Br} =\frac{14}{8}$

$\frac{R}{Br} =\frac{7}{4}$

R : Br = 7 : 4

b. The ratio of redheads to blondes is

$\frac{R}{Bl} =\frac{14}{6}$

$\frac{R}{Bl} =\frac{7}{3}$

R : Bl = 7 : 3

c. The ratio of blondes to brunettes is

$\frac{Bl}{Br} =\frac{6}{8}$

$\frac{Bl}{Br} =\frac{3}{4}$

Bl : Br = 3 : 4

d. The ratio of blondes to total students is

$\frac{Bl}{T} =\frac{6}{28}$

$\frac{Bl}{T} =\frac{3}{14}$

Bl : T = 3 : 14
