Multiply the Fractions	Result of Multiplying	Simplest Form	Mixed Number
a = (1/8)*(3/9)
b = (2/3)*(3/4)
c = (12/7)*(5/4)
a = (5/6)*4

Correct answer:

a =  1/24
b =  1/2
c =  15/7 = 2 ¹⁄₇
d =  10/3 = 3 ¹⁄₃

Step-by-step explanation:

$a=\frac{1}{8}\cdot \frac{3}{9}=\frac{1\cdot 3}{8\cdot 9}=\frac{3}{72}=\frac{1}{24}=0.0417$

$b=\frac{2}{3}\cdot \frac{3}{4}=\frac{2\cdot 3}{3\cdot 4}=\frac{6}{12}=\frac{1}{2}=0.5$

$c=\frac{12}{7}\cdot \frac{5}{4}=\frac{12\cdot 5}{7\cdot 4}=\frac{60}{28}=\frac{15}{7}=2\frac{1}{7}=2.1429$

$d=\frac{5}{6}\cdot 4=\frac{5\cdot 4}{6}=\frac{20}{6}=\frac{10}{3}=3\frac{1}{3}=3.3333$
