Answer:
x = 5/2 or 2.5
Step-by-step explanation:
1/4x = 5/8
To find the value of X;
We multiply both sides by 4
1/4 x × 4 = 5/8 × 4
x = 5/2 or 2.5

• Rise in percentage:
• let current number of pupils be n
First, I would reduce 3/15 and 15/21 to simplest form.
1/5, 5,7
You could list multiples of all your denominators. But in this case, because two of your denominators are already prime (5 and 7), you can just multiply the three denominators together.
5 x 7 x 8
This will give you the LCD
2) The area is 1.1 m^2 because to find the area the formula is width*length. SO you would separate it. It would be 0.9 * 1 = 0.9 and 0.4 * 0.5 = 0.2. Then you add it together. So it would be 1.1 m^2. The perimeter is all the sides added together so 4.2 m, but it says mm so you have to convert it and you get 4200.
4) Area is 1.16 cm^2. Again you would seperate it. So, 1 * 1 = 1 and .2 * .8 = .16. Then you add it together and get 1.16 cm^2. The perimeter is all the sides added up. You get 4.2 cm.
15 minutes is 25% of an hour. You can tell this because there are exactly 4 15 minute periods in one hour.
Hope this helped.
