Hint: The phrase "z is to 7, as 16 is to 56 " simply translates to the equation z%2F7=16%2F56. I'll let you solve the equation.

When working with proportions like this, always remember:
+a%2Fb+=+c%2Fd+ Cross multiply and you will find that ad = bc

Now we will set this up using your data:
+z%2F7+=+16%2F56+ cross multiplying gives us:
+56z+=+cross%287%2A16%29+=+112+

Divide both sides by 56:
+56z%2F56+=++112%2F56+
and we find that
z = 2
