A recipe for brownies calls for ¼ teaspoon of salt. The recipe makes 16 servings. How many teaspoons of salt are needed to make 35 servings?

Solve by proportion

(1/4) / 16  = N / 35

1/64  = N / 35    cross-multiply

35 * 1  = 64 * N

35 = 64 * N       divide both sides by 64

35/ 64  teaspoons  = N

Idk i think its (35/64)
