Answer :
We have
[tex]\frac{3.15}{0.45}[/tex]First, we need to do the operation above
[tex]\frac{3.15}{0.45}=7[/tex]So we will do all the options and if the result is the same as the result above the expression is equal to the given.
A. (3.15) × (0.45)=1.41
B. (3.15) ÷ (0.45)=7
C. (3.15) × 1/0.45=7
D. (3.15) ÷ 45/100=7
E. (3.15) ÷ 100/45=1.41
F. 0.45/3.15=0.14
As we can see the expressions that are equals are B,C,D
