Jack planted

Jack planted 1 1/4 rows of lettuce in the family garden. Rose planted 1 1/2 rows of broccoli, and Calvin planted 4 5/12 rows of beans. How many rows were planted in the garden?

Correct answer:

x =  7 ¹⁄₆ = 43/6

Step-by-step explanation:

$$\begin{gathered} J=1\frac{1}{4}=1+\frac{1}{4}=\frac{1\cdot 4+1}{4}=\frac{4+1}{4}=\frac{5}{4}=1\frac{1}{4}=1.25 \\ R=1\frac{1}{2}=1+\frac{1}{2}=\frac{1\cdot 2+1}{2}=\frac{2+1}{2}=\frac{3}{2}=1\frac{1}{2}=1.5 \\ C=4\frac{5}{12}=4+\frac{5}{12}=\frac{4\cdot 12+5}{12}=\frac{48+5}{12}=\frac{53}{12}=4\frac{5}{12}\doteq 4.4167 \\ x=J+R+C=\frac{5}{4}+\frac{3}{2}+\frac{53}{12}=\frac{15}{12}+\frac{18}{12}+\frac{53}{12}=\frac{15+18+53}{12}=\frac{86}{12}=\frac{43}{6}=7\frac{1}{6}=7.1667 \end{gathered}$$
