Determining the number of tablespoons by using equivalent expressions?

We can determine the number of tablespoons that are administered by using equivalent expressions.

From the standard conversion rate, we know that:

• 1 ml = 0.067628 tbsp
• 15 ml = 1.01442 tbsp

Using equivalent expressions:

7.5 mg/1.01442 tbsp = 5 mg/x tbsp

x = (1.01442 × 5)/7.5 tbsp

x = 0.67 tbsp

x = 0.7 tbsp per dose.
