Answer:
60:100, 6/10, 3/5, 6 to 10, etc.
Step-by-step explanation:
You take the number of girls over total students which is boys + girls. Since there's 40 boys and 60 girls, it's 60 girls to 100 students which can be written in several ways.
Lara can read 10 chapters in 4 hours.
At this rate, she can read half that many chapters in half the time.
So she reads 5 chapters in 2 hours.
So Lara reads 10 chapters in 4 hours,
+ 10 chapters in 4 more hours,
+ 5 chapters in 2 more hours.
That's 25 chapters in total, and 10 hours in total, ya? :)
Answer:
2 1/10
Steps:
You need both fractions to have the same denominator, you get 6/10 and 5/10
Subtract your fraction:
6/10 - 5/10 = 1/10
Then your whole numbers:
3 - 1 = 2
Then put your answers together:
2 1/10
To find the distance in one turn of the wheel you have to find the circumference of the wheel.

= 15.7 cm
therefore the rollerblade wheel will travel 15.7 cm per rotation
