​

Answer 1

50/3

72/5

18kg is the answer

Answer 2

Given

Weight of the empty cylinder =

16 4/5

1645 kg

Weight of the gas =

14 2/3

1423 kg

Find out

We have to determine the weight of the cylinder with gas

Solution

We have to add the values of the weight of the empty cylinder and the weight of the gas to get the weight of the cylinder with gas

weight of the cylinder with gas =

16 4/5

1645 kg +

14 2/3

1423 kg

On converting the mixed fractions to improper fractions we get

84/5

845 kg + 44/3

443 kg

Let us take the LCM of the denominators 5 and 3

LCM of 5 and 3 = 15

Hence252+220/15

252+22015 472/15

47215

Answer

Weight of the gas with cylinder =47215 kg
