How do you write 4 is to 16 as 12 is to 48 as a proportion in fractional notation
The proportion in fractional notation would be:
{{{4/16 = 12/48}}}
describe three ways to write the ratio that compares 4 electronic devices for every 3 people
1. 4:3 - In this format, the ratio is written with a colon (:) between the two numbers. So, it can be written as "4 to 3" or "4 for every 3".
2. 4/3 - This represents the ratio as a fraction. 4 is the numerator (the top number) and 3 is the denominator (the bottom number). It can be read as "4 over 3".
3. 4 per 3 - This phrasing indicates that for every group of 3 people, there are 4 electronic devices.
How do you write 5 to 1 as 20 is to 4 as a proportion in fractional notation
To write the proportion "5 to 1 as 20 is to 4" in fractional notation, we can express it as:
{{{5/1 = 20/4}}}
You fill your car with 15 gallons of gas at the cost of $45. using fractional notation, how do you write a proportion that shows how much 5 gallons of gas will cost? use x to represent the unknown cost
To write the proportion that shows how much 5 gallons of gas will cost, we can set up the following equation using fractional notation:
{{{15/45 = 5/x}}}
Here, x represents the unknown cost of 5 gallons of gas.
Determine if 2.5/10 = 12/48 or 2.5/48 = 12/24 is a proportion
To determine if 2.5/10 = 12/48 is a proportion, we can cross-multiply and check if the two products are equal.
Cross-multiplying:
2.5 * 48 = 10 * 12
120 = 120
Since the products are equal, it means that 2.5/10 = 12/48 is indeed a proportion.
To determine if 2.5/48 = 12/24 is a proportion, we can also cross-multiply:
Cross-multiplying:
2.5 * 24 = 48 * 12
60 = 576
Since the products are not equal (60 ≠ 576), it means that 2.5/48 = 12/24 is not a proportion.
