First we need to make these two numbers into improper fractions
1 [tex]\frac{5}{7}[/tex] = [tex]\frac{12}{7}[/tex]
4 [tex]\frac{2}{7}[/tex] = [tex]\frac{30}{7}[/tex]
Now on the next step,
To divide a fraction by another fraction, we must flip the second number upside down.... watch
[tex]\frac{12}{7}[/tex] ÷ [tex]\frac{7}{30}[/tex] = then we change the divide ( ÷ ) sign to a multiplication ( × )
[tex]\frac{12}{7}[/tex] × [tex]\frac{7}{30}[/tex] = [tex]\frac{84}{210}[/tex]
simplify
[tex]\frac{84}{210}[/tex] ⇒ [tex]\frac{12}{30}[/tex]
