So we know that all together there is 1560g. So what we do is add the ratio numbers together which is 4+3+1. This gives us 8. Next, what we can do is how much is 1 (ratio). So we do 1560g/8. This gives us 195g. Now the last step is to multiply 195g with each ratio number given. So milk is represented as 4. So therefore milk would be 4 multiplied by 195g. This means milk= 780g. Tea = 3 multiplied by 195g. Thus, this gives us 585g. The last one which is pearls is 195g as it is multiplied by 1. To check the answer, you can add the three numbers which are 780g+ 585g+195g= 1560g.
