Please could I have some help with following Q:
There are 816 pupils in a school. There are 28 more girls than boys in the school.How many girls are there?
The answer is 422.
*816 - 28 = 788 --> We take away the number of girls
*788/2 = 394 --> We have to split the number in half in order to work out the number of boys and girls
*There are 394 boys and at least 394 girls
*394 + 28 = 422 --> We have to add the 28 girls back to find the total number of girls in the school
