At a school number of boys to girls 11:9 there are 124 more boys than girls work out the number of student at the school

If the ratio of boys to girls is 11:9 and there are 124 more boys than girls:

Let's say that the number of boys is 11x and the number of girls is 9x.

So, 11x = 9x + 124

2x = 124

x = 62

The total number of students = Number of boys + number of girls

                                                 = 11x + 9x

                                                 = 20x

                                                 = 1240 students

Thus, the total number of students attending the school is 1240.

Sam has traveled a distance of 9/16 of a mile

Step-by-step explanation:

Here, we want to calculate the distance traveled by Sam so far.

The distance between his home and the library is 3/4 mile = 0.75 mile

Now, he is 1/4 of the way there; this means that he has traveled a total of 3/4 of the total distance.

By being at a distance which is just a quarter of the total, it means he has already traveled 3/4 of the journey.

So the distance traveled so far will be 3/4 of 0.75 or more simply 3/4 of 3/4 = 3/4 * 3/4 = 9/16 of a mile
