28 to 42 means 28/42
We now reduce 28/42 to lowest terms.
28 ÷ 7 = 4
42 ÷ 7 = 6
We now have 4/6.
We now reduce 4/6.
4 ÷ 2 = 2
6 ÷ 2 = 3
Final answer: 2/3
You can just google this, here is what popped up when I searched it so I could give an exact answer..... Variability<span> is the extent to which data points in a statistical distribution or data set diverge from the average, or mean, value as well as the extent to which these data points differ from each other. There are four commonly used measures of </span>variability<span>: range, mean, variance and standard deviation.</span>
Answer:
Actual Height = 27.11 m
Step-by-step explanation:
Given:
Height of model rocket = 4.5 % of actual Height
Model Height = 1.22 m
To Find:
Actual Height of rocket = ?
Solution:
We have to Find the Actual Height of the rocket
Let actual height be x
Now it is given that
Height of model rocket = 4.5 % of actual Height
As we have the values so putting it in it becomes
1.22 = 4.5 % * x
it could be written as
Multiplying both sides by 
it becomes
1.22* = x
= x
27.11 m =x
or
Actual Height = 27.11 m
Given: £90 is divided among Aahil, James and Merav in the ratio 1:3:5.
To find: How much Merav gets.
Answer:
Let's assume the shares of each to be 'x'.
This implies that 1x + 3x + 5x = 90.
9x = 90
x = 90/9
x = 10
Substituting this value of x in the ratio,
- 1 × 10 = 10 [<em>Aahil's share</em>]
- 3 × 10 = 30 [<em>James' share</em>]
- 5 × 10 = 50 [<em>Merav's share</em>]
Therefore, Merav gets £50.
Hope it helps. :)
