To solve this problem, set up a proportion:
3/1 = x/145
Cross-multiply:
1 * x = 3 * 145
Simplify:
x = 435
So, a 145-pound person should drink 435 ounces of water. Therefore, the correct response is 435 oz.
To solve this ratio problem, we need to set up a proportion between the amount of water and the person's weight.
The given information tells us that for every pound, three quarters of an ounce of water should be consumed.
Let's represent the unknown amount of water as "x" ounces. We can set up the proportion as follows:
3/4 = x/145
To solve for "x," we can cross multiply:
4x = 3 * 145
Multiply 3 by 145:
4x = 435
Now, we can solve for "x" by dividing both sides of the equation by 4:
x = 435/4
Calculating this division, we get:
x ≈ 108.75
Therefore, a 145-pound person should drink approximately 108.75 ounces of water.
Rounded to the nearest hundredth, the answer is 108.75 oz.
To solve this problem, we can use proportions.
Given that some doctors recommend drinking three quarters of an ounce of water for every pound that you weigh, we can set up the proportion:
(3/4 ounce)/(1 pound) = (x ounces)/(145 pounds)
To cross multiply and solve for x, we get:
(3/4) * 145 = x
x ≈ 108.75
Therefore, a 145-pound person should drink approximately 108.75 ounces of water.
Rounding to the nearest hundredth, the answer is 108.75 oz.
