Certainly! Let's solve the expression step-by-step.
Given:
[tex]\[ -48a \div 8 \][/tex]
where [tex]\( a = 1 \)[/tex].
1. Substitute [tex]\( a = 1 \)[/tex] into the expression:
[tex]\[ -48 \cdot 1 \div 8 \][/tex]
2. Next, we perform the multiplication first:
[tex]\[ -48 \cdot 1 = -48 \][/tex]
3. Now, we need to divide the result by 8:
[tex]\[ -48 \div 8 \][/tex]
4. Perform the division:
[tex]\[ -48 \div 8 = -6.0 \][/tex]
So, the answer in simplest form is:
[tex]\[
\boxed{-6.0}
\][/tex]
