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
\(\frac{ \frac{23}{4} }{ \frac{3}{4} }\)
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 (\(\frac{ \frac{23}{4} }{ \frac{3}{4} }\)) by 1 or x/x or \(\frac{ \frac{4}{3} }{ \frac{4}{3} }\)
so
\(\frac{ \frac{23}{4} }{ \frac{3}{4} }\) times \(\frac{ \frac{4}{3} }{ \frac{4}{3} }\) =\(\frac{ \frac{92}{12} }{ \frac{12}{12} }\) =\(\frac{ \frac{92}{12} }{1 }\) =\(\frac{ 92}{ 12}\) =\(\frac{ 46}{ 6}\)=\(\frac{ 23}{ 3}\)=7 and 2/3
answer is 7 and 2/3 miles per hour
