By what number should we multiply -15/28, so that the product may be -5/7?
Answers
Answer:
4/3
Step-by-step explanation:
First, multiply -15/28 with 4/3.
Second, you need to cross 28 with 7 and 15 with 3.
Since 28 divided by 4 is 7, and 15 divided by 3 is 5, therefore this gives the result of 5/7 (with negative sign).
Hope it helps. Thanks!
Answer:
Step-by-step explanation:
Let the number be x
According to question,
x × 20 /−15 =7 /−5
⇒x=
7×(−15) / (−5)×20
⇒x= 21/22
So, The other number is 21/22.

To create a poster with dimensions 13x13in, you will need to make multiple enlargements using the given settings. You will need approximately 1 enlargement.
To create a poster with dimensions 13x13in from a square picture with dimensions 6x6in, you will need to make multiple enlargements or reductions using the given settings. Since the desired dimensions are larger than the original picture, you will need to use the enlargement setting. The enlargement factor given is 140%, which means you need to increase the dimensions of the picture by 140%. Here's how many enlargements you will need:
- Calculate the growth factor by subtracting 100% from the enlargement factor: 140% - 100% = 40%
- Calculate the number of enlargements needed by dividing the growth factor by the enlargement factor: 40% / 140% ≈ 0.2857 (rounded to 5 decimal places)
Therefore, you will need to make approximately 0.2857 multiple enlargements, which can be rounded to 0.29 or 1 enlargement.

Answer:
1. 3x(4-x)
2. 20(1-12x^2)
Step-by-step explanation:
1. Both of the monomials have an x and can be divided by 3. You can factor out 3x, getting the equation I wrote out on the answer part.
2. Both of the monomials can be divided by 20, so you can once again factor out 20, getting the equation I wrote out on the answer part.

What is Unitary Method?
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Number of flowers= 48
Number of flowers in each vase = 6
So, number of vase can be made
= 48/6
= 8 vases
Now, if each vase cost $2 then cost 8 vase
= 8 x 2
= $16.
