Answer :
Answer:
[tex]1\frac{3}{4} \ hours[/tex] more Sonia study than James.
Step-by-step explanation:
Given:
Sonia studied for 2 1/3 hours for the math test james studied 3/4 as long as Sonia.
Now, to find hours more Sonia study than james.
Sonia studied = [tex]\frac{7}{3} \ hours.[/tex]
James studied = [tex]\frac{3}{4} \ hour.[/tex]
Now, to get the more hours Sonia study than James we subtract the hour James studied from hours Sonia studied:
[tex]\frac{7}{3} -\frac{3}{4}[/tex]
[tex]=\frac{28-9}{12}[/tex]
[tex]=\frac{21}{12}[/tex]
[tex]=\frac{7}{4}[/tex]
[tex]=1\frac{3}{4}\ hours.[/tex]
Therefore, [tex]1\frac{3}{4} \ hours[/tex] more Sonia study than James.
