Answer:
1080
Step-by-step explanation:
looking at the ratio of 1 : 3 : 6, we can say that the pupils are divided into 1 + 3 + 6 = 10 "parts".
Indian are 1 part, Malay are 3 parts, and Chinese are 6 parts.
So 3x (3 parts of malay) is 360 more than 1x (1 part of Indian). Thus:
3x - 360 = x
2x = 360
x = 180
We know chinese is 6 parts, or 6x, so Chinese would be 6 (180) = 1080
Hence, there are 1080 chinese pupils

5 1/2 + 5 7/8 + 6 1/2 + 3 1/8 = ???
First take the two 1/2's and Since 4 times 2 equals 8, multiply the denominator & numerator by 4.
You will get two 4/8's
4/8 + 4/8= 8/8
8/8= 1 whole.
Now take 7/8 + 1/8 = 8/8 that will turn into 1 whole too.
5+5+6+3= 19.
Now take your two added wholes( 2 wholes) and add.
2+19= 21
There is your answer is 21 pounds.
