We know that for every 5 red bricks there were 2 gray bricks.
The total amount of red bricks and grey bricks in this sample is 7.
5 red bricks + 2 grey bricks = 7 bricks
Now, we divide 175 "total number of bricks used" by 7 "5 red bricks + 2 grey bricks = 7 bricks" and we will get a quotient of 25.
Now we know that 25 bricks is of the wall. The gray bricks are
so we can multiply 25 by 2 and we will get a product of 50. If 1/7 = 25 grey bricks so 2/7 would be the grey bricks.
175 - 50 = number of red bricks.
Therefore, there were 125 red bricks.

I can't imagine. All you have to do is pick any old number, divide the
top and bottom of the fraction by it, and you'll have a new fraction that's
equivalent to 50/100 . And if the number you pick is 2, 5, 10, or 25,
then the new fraction will even have whole numbers on top and bottom.
You can even pick any old number, multiply the top and bottom of the
fraction by it, and you'll have a new fraction that's equivalent to 50/100 .
Can't imagine what's so hard about that.

steps:
1. subtract 140 from both sides. now you have: 15p (is greater than or equal to) 60.
2. divide both sides by 15.
3. simplify. now, the answer is p (is greater than or equal to) 4.
140+15x≥200
15x≥200-140
15x≥60
x≥60/15
x≥4

Straight from the question, the ratio is 24/18 .
That can be simplified if we can find a common factor
of both numbers.
They have common factors of 1, 2, 3, and 6 .
Divide the top and bottom by 6, and the simplified form is 4/3 .
= 24/18
= (24/6) / (18/6)
= 4/3
= 4:3
The final answer is D. 4:3~

Step-by-step explanation:
To “associate” means to connect or join with something. According to the associative property of multiplication, the product of three or more numbers remains the same regardless of how the numbers are grouped. Here's an example of how the product does not change irrespective of how the factors are grouped.
