Can anyone help with this question? -- The total mass of 3 big sacks of rice is the same as the total mass of 5 small sacks of rice. A big sack of rice is 2.2kg heavier than a small sack of rice. What is the mass of 5 small sacks of rice?

tia :-)

( u --> mass of small sack )

3u + 6.6 = 5u

2u--> 6.6

1u = 3.3

5u --> 5*3.3= __kg
