Terry 40 kg

40+70=110

The combined weight of Terry and Janice is 110 lb.

Given that, terry weighs 40kg Janice weighs 2 3/4 lb less than terry.

We need to find what is their combined weight.

What is weight?

Weight is the measure of how heavy an object is. Weight is measured in standard customary units. The mass of an object is the amount of material it contains. Mass is measured in standard metric units.

We know the main standard unit of mass or weight is kilogram which we write in short as 'kg'. 1000th part of this kilogram is gram which is written in short as 'g'. Thus 1000 gram = 1 kilogram and 1 kilogram = 1000 gram. i.e. 1000 g = 1 kg and 1 kg = 1000 g.

Now, we can write 2 3/4 as 11/4.

Terry weighs 40kg Janice weighs 2 3/4 lb less than Terry=40.11/4-40

=110-40=70kg Janice

Total weight =40+70=110 lb

Therefore, the combined weight of Terry and Janice is 110 lb.
