Given the equation 2s = 3 1/2, fill in the blank with the value that models the equation. The recipe requires an amount of sugar than flour. The recipe needs cups of flour.

The recipe requires an amount of sugar than flour. The recipe needs cups of flour.

To model the equation 2s = 3 1/2, we need to solve for s in order to find the amount of sugar needed in the recipe.

Let's start by converting the mixed number 3 1/2 into an improper fraction.

3 1/2 = (2 * 3) + 1/2 = 7/2

So, the equation becomes:

2s = 7/2

To find the value that models this equation, we need to divide both sides of the equation by 2:

s = (7/2) / 2 = 7/4

Therefore, the value that models the equation is 7/4.
