What are ratios and proportion?
Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other. A statement expressing the equality of two ratios A:B and C:D is called a proportion. We can express proportion as -
A : B ∷ C : D
AND
A x D = B x C
Product of extremes equal to product of means.
Given is in a school 3/5 pupils are boys and 240 are girls
We can write -
Assume that the total children are [x]. Then, we can write the equation as-
3x/5 + 240 = x
x - 3x/5 = 240
0.4x = 240
x = 600
Number of boys = 3/5 x 600 = 3 x 120 = 360
Total children = 600
Therefore, the number of boys are 360 and Total children are 600

according to question,
2/5 of x = 240
thus, 2/5 * x = 240
2x = 1200
thus, x = 600.
Thus, no. of boys = 600 - 240 = 360
thus, total children = 360 + 240 = 600

Answer: Fraction of red tulips of Solan is greater than fraction of red tulips of Julie by 0.75-0.5=0.25.
Step-by-step explanation:
Since we have given that
In case of Solan:
Number of red tulips = 15
Total number of tulips = 20
In case of Julie :
Number of red tulips = 10
Total number of tulips = 20
So, Fraction of red tulips of Solan is given by
Fraction of red tulips of Julie is given by
So, Fraction of red tulips of Solan is greater than fraction of red tulips of Julie by 0.75-0.5=0.25.
Answer:
Solan's tulip fraction was 1.5 times greater than Julie's.
Step-by-step explanation:
15/20 of Solan's tulips were red, while 10/20 of Julie's were red.
Solan's tulip fraction was 1.5 times greater than Julie's.

The equation (2 x 4) x 7 = 2 x (7 x 4) demonstrates the Associative Property of multiplication.
The Associative Property states that for any three numbers a, b, and c, the way we group them in a multiplication operation will not change the final result. Mathematically, it can be expressed as:
(a x b) x c = a x (b x c)
In the given equation, we have (2 x 4) x 7 on the left side and 2 x (7 x 4) on the right side. Let's compute each side step-by-step to see how the property applies.
Left side: (2 x 4) x 7 = 8 x 7 = 56
Right side: 2 x (7 x 4) = 2 x 28 = 56
As we can see, both sides result in 56, demonstrating that the outcome remains consistent, irrespective of how we group the numbers. In this case, we multiplied 2 and 4 first (left side) and 7 and 4 first (right side) before performing the final multiplication. The Associative Property assures us that we will always get the same answer, regardless of the grouping.

( 2 x 4 ) x 7 = 2 x (7 x 4 ) represents the associative property of multiplication. The associative property states of multiplication states, that you can multiply even how the numbers are grouped.
You can test this you're self.
1. Multiply 2*4=8 8 *7=56
2. 7*4=28 28*2=56
In conclusion, ( 2 x 4 ) x 7 = 2 x (7 x 4 ), uses the associative property of multiplication.
Hope this helps :)
