Solution

Step 1. Finding the sum of weights of potatoes, onions, and tomatoes:

Given,

The weight of potatoes =3kg450g=3.450kg(Since1000g=1kg,so450g=0.450kg)

The weight of onions =2kg10g=2.010kg

The weight of tomatoes =1kg750g=1.750kg

The sum of the weights of potatoes, onions, and tomatoes =3.450+2.010+1.750

=7.210kg

So, the sum of weights of potatoes, onions, and tomatoes is 7.210kg.

Step 2. Finding the weight of green vegetables:

Given the total weight of vegetables =10kg

The weight of green vegetables =Total weight of vegetables - Sum of weights of potatoes, onions, and tomatoes.

=10-7.210

=10.000-7.210

=2.790kg

=2kg790g

Hence, the weight of green vegetables is 2kg790g.
