Answer:
Jada used 1/2 of the pancake mix in the box
Step-by-step explanation:
we know that
[tex]1\frac{3}{4}\ pounds[/tex] -----> represent the 100% of the box
so
by proportion
Find what fraction represent [tex]\frac{7}{8}\ pounds[/tex]
First convert mixed number to an improper fraction
[tex]1\frac{3}{4}\ pounds=\frac{1*3+4}{4}=\frac{7}{4}\ pounds[/tex]
[tex]\frac{100}{(7/4)}=\frac{x}{(7/8)}\\ \\x= 100*(7/8)/(7/4)\\ \\x=50\%[/tex]
Convert the percentage into fraction
[tex]50\%=50/100=1/2[/tex]
