Answer:

x = 0.327

Step-by-step explanation:

[tex]\frac{21}{4}[/tex] = [tex]\frac{12}{7}[/tex] ÷ x

[tex]\frac{21}{4}[/tex] = [tex]\frac{12}{7}[/tex] × [tex]\frac{1}{x}[/tex]

[tex]\frac{21}{4}[/tex] = [tex]\frac{12}{7x}[/tex]

[tex]\frac{21}{4}[/tex] x 7x = 12

[tex]\frac{147x}{4}[/tex] = 12

147x = 12 x 4

x = 48 ÷ 147

x = 0.327
