so miles per hour
self explanatory
speed is miles per hour
miles divided by hours
per hour means per 1 hour so
miles per 1 hour
so therefor we convert it to a fraction and make the bottom equal to 1
convert 5 and 3/4 to improper fracitons fors
5 and 3/4=20/4+3/4=23/4
so we have
[tex] \frac{ \frac{23}{4} }{ \frac{3}{4} } [/tex]
to convert the bottom number to one, we take it individually
3/4 times what=1
multiply both sides by 4/3
12/12 times what=4/3
1 times what=4/3
what=4/3
answe ris 4/3
to make the fraction equivilent, we must multiply the whole fraction ([tex] \frac{ \frac{23}{4} }{ \frac{3}{4} } [/tex]) by 1 or x/x or [tex] \frac{ \frac{4}{3} }{ \frac{4}{3} } [/tex]
so
[tex] \frac{ \frac{23}{4} }{ \frac{3}{4} } [/tex] times [tex] \frac{ \frac{4}{3} }{ \frac{4}{3} } [/tex] =[tex] \frac{ \frac{92}{12} }{ \frac{12}{12} } [/tex] =[tex] \frac{ \frac{92}{12} }{1 } [/tex] =[tex] \frac{ 92}{ 12} [/tex] =[tex] \frac{ 46}{ 6} [/tex]=[tex] \frac{ 23}{ 3} [/tex]=7 and 2/3
answer is 7 and 2/3 miles per hour
