Answer:
[tex]question \: \: 4. : \\ 320 \: miles = 3 \: inches. \\ question \: \: 6. : \\586 \frac{2}{3} \: miles = 5.5 \: inches.\\ question \: \: 8. : \\ 9 \frac{1}{10} \: inches =1,092 \: feets.[/tex]
Step-by-step explanation:
[tex]question \: \: 4. : \\ if \: 80 \: miles = \frac{3}{4} \: inch \\ 320 \: miles = \frac{ \frac{3}{4} \: inch \times 320 \: miles }{80 \: miles} \\ \\ 320 \: miles \: = \frac{3}{4} \: inch \: \times 4 \\ 320 \: miles = 3 \: inches. \\ \\ question \: \: 6. : \\ if \: 80 \: miles = \frac{3}{4} \: inch \\ \\ 586 \frac{2}{3} \: miles = \frac{ \frac{3}{4} \: inches \times586 \frac{2}{3} \: miles }{80 \: miles} \\ \\ 586 \frac{2}{3} \: miles = \frac{440}{80} \: inches\\ \\ 586 \frac{2}{3} \: miles = 5.5 \: inches. \\ \\ question \: \: 8. : \\ if \: 1 \: inche = 120 \: feets \\ 9 \frac{1}{10} \: inches = \frac{9 \frac{1}{10} \: inches \times 120 \: feets }{1 \: inche} \\ \\ 9 \frac{1}{10} \: inches = \frac{91 \times 120}{10} \: feets \\ \\ 9 \frac{1}{10} \: inches =1,092 \: feets.[/tex]
