Question

Consider A=111 cm·kg and B=37 mg·km Please identify which operations are possible, and which are not. If the operation is possible, also check the given result. You cannot add 5m and 3s, so "this operation is impossible." You can add 5m and 3cm, so "this operation is possible" - however, the answer 8m would false. You can multiply A and B, and get 0.04107 m·kg You can add A and B, and get 1.147 m·kg You can multiply A and B, and get 0.04107 m2kg2 You can divide A by B, and get 30 You can add A and B2, and get 1.111369 m·kg

Explanation / Answer

unit of A are of ,mass*length while for B also,it is same so we can do all operation i.e.sum,subtract,division and multiplication

But we need to convert into same unit

Converting into cm.kg

A=111 cm.kg

B=37*(100000/1000000)=3.7 cm.Kg

so A+B=114.7 cm.kg

A-B=107.3 cm.Kg

A*B=410.7 (cm.kg)^2

A/B=30
