$16-:4*2-7 = 16-:4*2-7 = 4*2-7 = 8-7 = 1$

Use the PEMDAS mnemonic to provide the order of application of operations:

Parentheses
Exponents
Multiplication & Division
Addition & Subtraction

We have no parentheses, exponents or addition to process, so start with multiplication and division, then subtraction:

$color(red)(16-:4)*2-7 = color(red)(4*2)-7 = color(red)(8-7) = 1$
