Tablespoon of salt

Mrs. Monika uses 3/4 tablespoons of salt for every kilogram of ground pork. How many tablespoons of salt will she use for 3 1/2 kilograms of ground pork?

Correct answer:

s =  2 ⁵⁄₈ = 21/8

Step-by-step explanation:

$$\begin{gathered} m_1=3\frac{1}{2}=3+\frac{1}{2}=\frac{3\cdot 2+1}{2}=\frac{6+1}{2}=\frac{7}{2}=3\frac{1}{2}=3.5 \\ s=\frac{3}{4}\cdot m_1=\frac{3}{4}\cdot \frac{7}{2}=\frac{3\cdot 7}{4\cdot 2}=\frac{21}{8}=2\frac{5}{8}=2.625 \end{gathered}$$
