Question

Find the difference between the products of 2.5 and 7.5 and the sum of 2.75 and 9.55​

Answer 1

Explanation:

The product of
`2.5` and
`7.5` is
`(2.5)(7.5)=(5/2)(15/2)=75/4=18.75`.

The sum of
`2.75` and
`9.55` is
`2.75+9.55=(2+9)+(0.75+0.55)=11+1.3=12.3`.

The difference between these is
`18.75-12.3=(18-12)+(0.75-0.3)=6+0.45=6.45`.

So, the answer is
`\boxed{6.45}` and we're done!
