Jason has five equally massed lead fishing weights, each weighing 250 grams. What is the total mass of the five lead fishing wei
algol [13]

Answer:

1250 g=1.25 Kg

Explanation:

We are given that Jason has five fishes of equally massed lead fish weights.

Weigh of each fish =250 grams

We have to find the value of total mass of the five lead fishing weights

Total number of fishes=5

In order to find the total mass we will use unitary method

Total mass is obtained by multiplying the total number of fishes with weight of one fish

Total mass=5\times 250

Total mass of five fishes=1250 g

1 kg =1000g

Then 1250 g=\frac{1250}{1000}=1.25 Kg

Hence, total mass of five lead fishing weights=1250 g=1.25 Kg
