Understanding the Ratio

A ratio is a way to express the relationship between two or more numbers. In this case, we have a ratio of 4:3, which means that for every 4 units of one quantity, there are 3 units of another quantity. Ratios can be used to compare different quantities, and they can also be used to solve problems involving proportions.

Decreasing 72 in the Ratio 4:3

To decrease 72 in the ratio 4:3, we need to find the value of one part of the ratio and then multiply it by a fraction to get the new value. Let's start by finding the value of one part of the ratio.

Finding the Value of One Part of the Ratio

To find the value of one part of the ratio, we need to divide the total value (72) by the sum of the parts (4+3=7). This will give us the value of one part of the ratio.

# Calculate the value of one part of the ratio
total_value = 72
sum_of_parts = 4 + 3
value_of_one_part = total_value / sum_of_parts
print(value_of_one_part)

The value of one part of the ratio is 10.29 (rounded to two decimal places).

Decreasing 72 in the Ratio 4:3

Now that we have the value of one part of the ratio, we can decrease 72 in the ratio 4:3 by multiplying the value of one part by a fraction. Let's say we want to decrease 72 by 20%. We can multiply the value of one part by 0.8 (1 - 0.2) to get the new value.

# Decrease 72 in the ratio 4:3
value_of_one_part = 10.29
fraction = 0.8
new_value = value_of_one_part * fraction
print(new_value)

The new value is 8.23 (rounded to two decimal places).

Decreasing 72 in the Ratio 4:3 by a Different Percentage

We can also decrease 72 in the ratio 4:3 by a different percentage. Let's say we want to decrease 72 by 30%. We can multiply the value of one part by 0.7 (1 - 0.3) to get the new value.

# Decrease 72 in the ratio 4:3 by a different percentage
value_of_one_part = 10.29
fraction = 0.7
new_value = value_of_one_part * fraction
print(new_value)

The new value is 7.20 (rounded to two decimal places).
