Answer:
The mistake is to make [tex]\frac{15}{16}=\frac{3}{5}[/tex]
The correct answer [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
This is the operation performed by Kali:
[tex]\frac{15}{16}*\frac{4}{5}=\frac{4}{5}*\frac{3}{5}=\frac{12}{25}[/tex]
but 15/16 ≠3/5, so knowing this [tex]\frac{a}{b}*\frac{c}{d}=\frac{a}{d}*\frac{c}{b}[/tex] , then
[tex]\frac{15}{16}*\frac{4}{5}=\frac{15}{5}*\frac{4}{16}=3*\frac{1}{4}=\frac{3}{4}[/tex]
