The recommended daily allowance of methionine for an adult is 15 mg per kg of body mass. Tuna contains 755 mg of methionine per 100 g portion. Calculate the mass, in grams, of tuna that would provide the RDA of methionine for a 60 kg adult.

15mg per kilo recommended dose
15x60 = 900mg recommended dose for a 60kg adult
There is 755mg per 100g portion of tuna
So 900/755 = 1.19 times the amount in 100g of tuna is the recommended dose
1.19 x 100 = 119
119g of tuna is the amount that would provide the total recommended dose for a 60kg adult
