On a packet of brown rice it says 'When 60g of rice is cooked, it will weigh 145g.' If Katy has 100g of brown rice, how much will it weigh when cooked?'
- Find by what ratio the weigh of rice has increased.
If the rice increases in weight from 60g to 145g, the factor by which it increases is: (145/60) = 2.4166...
- Multiply the amount of rice Katy has by this factor.
Katy has 100g of rice, therefore: 100 x 2.4166... = 241.66... = 242g (3sf)
