You add 5+7 so the total ratio is 12. then divide 48/12=4. you then multiply the given ration 5:7 by 4=20:28. 20 + 28 is 48 students which is given. so there are 28 girls and 20 boys which means there are 8 more girls than boys.
Answer:
Step-by-step explanation:
Using the hint, write a and b in the following prime factorization:
where for i ≠ j.
Then by the formulae for gcd(a,b) and lcm(a,b) we know that:
Note that the expression for all i, since if the minimum is, <em>without loss of generality</em>, , then the maximum must be , and viceversa. Then, it is straightforward to verify that when we multiply gcd(a, b) and lcm(a, b) its prime factorization matches the prime factorization of ab, and so we can see the equaility holds:
