the weight of 3 different pencils is 50g,30g and 40g.Work out their average weight.
(50 + 30 + 40)/3 = ?
it is 40g..
Yes.
To work out the average weight of the three pencils, you need to find the sum of their weights and divide it by the number of pencils.
Step 1: Add up the weights of the three pencils.
- 50g + 30g + 40g = 120g
Step 2: Divide the sum of the weights by the number of pencils.
- 120g ÷ 3 pencils = 40g
Therefore, the average weight of the three pencils is 40 grams.
