Answer:
Option B is correct.
2.0 fluid ounces of milk are required to provide 67.5 milligrams of calcium
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal.
As per the given statement: Drinking 7 fluid ounces of milk provides 236.25 milligrams of calcium.
Let x be the fluid ounce of milk.
then, by using proportion method we have;
[tex]\frac{7}{236.25} = \frac{x}{67.5}[/tex] ......[1]
Cross multiply states that an equation of fractions when each side consists of a fraction with a single denominator by multiplying the numerator of each side by the denominator of the other side and then, equating the two products obtained.
Apply cross multiply in [1];
[tex]7 \times 67.5 = 236.25 \times x[/tex]
Simplify:
[tex]472.5 = 236.25x[/tex]
Divide 236.25 we get;
[tex]x = \frac{472.5}{236.25}[/tex]
Simplify:
x = 2.0
therefore, 2.0 fluid ounces of milk are required to provide 67.5 milligrams of calcium
