Hey there!

If Daniel gets 4 out of 5 right thats a 4:5 ratio. If we let x be the number of questions he gets asked, and y be the number of questions he get right (64), we can solve for x.

\(x*\frac{4}{5}=y\)

\(x*\frac{4}{5}=64\)

\(x=\frac{64}{\frac{4}{5}}\)

\(x=80\)

Now you can figure out how many he missed!

Hope this helped :)
