Anton and Maria shared 240 stamps in a ratio 4:2.How many stamps did Maria
get?
Daniel and Imee shared a bag of rice in the ratio 4:5.Daniel receives 16
kg of the rice . What was the mass of the bag of rice that was shared?
My work:
4:5-16/9=1.77777777778/1.8
=1.8*9=16.2 kg
Is it correct

No.
Set up a ratio, cross multiply, and solve for x.
4/5 = 16/x (ratio, with "x" where the unknown is)
4x = 80 (after cross multiplying)
x = 20 (after dividing both sides by 4)
Now you try the second one.

This one is a bit different.
In the first one, the "16" was the value of one of the terms of the ratio.
In this one, the "240" is the sum of the terms of the ratio.
Let Anton's number of stamps be 4x
let Maria's number be 2x
4x + 2x = 240
x = 40
Maria has 2x or 80 stamps
