Answer:
The two parts of 72 that are in a 5:7 ratio are 30 and 42.
Step-by-step explanation:
To find the two parts of 72 that are in a 5:7 ratio, we can set up the following equation:
5x + 7x = 72
Combining like terms, we get:
12x = 72
Dividing both sides by 12, we get:
x = 6
Now, we can find the two parts:
One part = 5x = 5 * 6 = 30
The other part = 7x = 7 * 6 = 42
