Answer 1

$\huge \bf {Question}:—$

$\boxed{\bf \: 4(3.5 - 1.5) - 1/2}$

$\bf\huge Solution:—$

$\sf \longmapsto \: 4*(3.5-1.5)-1/2$

$\boxed{\bf \: Convert \: 1/2 \: i nto \: Decimal:—}$

$\sf \longmapsto \: 4*(3.5-1.5)-0.5$

$\boxed{\bf \: Subtract \: 3.5-1.5 :—\: (2 \: is \: the \: result)}$

$\sf \longmapsto \: 4*(2) - 0.5$

$\boxed{\bf Multiply \: 4 \: and \: 2:—(8 \: is \: the \: result)}$

$\sf \longmapsto8-0.5$

$\boxed{\bf \: Simply \: Subtract:—}$

$\sf \longmapsto7.5$

$\sf\longmapsto 15/2$

$\boxed{\bf \: Mixed \: Fraction:—}$

$\boxed{\sf\longmapsto 7 \dfrac{1}{2} }$

________________________________

$\boxed{\bf Solving \: in \: another \: way:—}$

$\sf \longmapsto4*2-1/2$

$\sf \longmapsto4*(2)-1/2$

$\sf \longmapsto8-1/2$

$\sf \longmapsto \: 15/2$

$\boxed{\bf \: Mixed \: Fraction:—}$

$\boxed{\sf \longmapsto \: 7 \dfrac{1}{2} }$

$\boxed{\bf \: \: Answer \: i s \: Option \: B}$

$\boxed{\huge\sf \: (B) \: \bf \: 7\dfrac{1}{2}}$

Answer 2

$\huge\textbf{Hey there!}$

$\mathbf{4(3.5 - 1.5) - \dfrac{1}{2}}\\\\\mathbf{\rightarrow 4(2) - \dfrac{1}{2}}\\\\\mathbf{\rightarrow 8 - \dfrac{1}{2}}\\\\\mathbf{\rightarrow \dfrac{15}{2} \approx 7.5 \approx \boxed{\bf 7 \dfrac{1}{2}}}\\\\\\\\\huge\boxed{\textbf{Therefore, your answer is: \boxed{\mathsf{Option \ B. \ 7 \dfrac{1}{2}}}}}\huge\checkmark$

$\huge\textbf{Good luck on your assignment \& enjoy}\\\huge\textbf{your day!}$
