Answer:
Step-by-step explanation:
The product of [tex]2.5[/tex] and [tex]7.5[/tex] is [tex](2.5)(7.5)=(5/2)(15/2)=75/4=18.75[/tex].
The sum of [tex]2.75[/tex] and [tex]9.55[/tex] is [tex]2.75+9.55=(2+9)+(0.75+0.55)=11+1.3=12.3[/tex].
The difference between these is [tex]18.75-12.3=(18-12)+(0.75-0.3)=6+0.45=6.45[/tex].
So, the answer is [tex]\boxed{6.45}[/tex] and we're done!
