Answer:
8
Step-by-step explanation:
Sum the parts of the ratio 4 + 2 = 6 parts
Divide 24 by 6 to find the value of one part of the ratio
24 ÷ 6 = 4 ← value of 1 part, thus
number of boys = 4 × 4 = 16
number of girls = 2 × 4 = 8
Hence there are 8 more boys than girls
Since it says the sum of any number not one in specific then the value will be x, plus the sum of 7,
