Question$\triangle D E F \sim \triangle J K L$. What is $E F$ ? (A) 4.2 (B) 3.6 (C) 2.0 (D) 0.9

Studdy Solution
Solve the proportion to find $EF$. Cross-multiply to solve for $EF$:
$3 \times 1.8 = 6 \times EF$
$5.4 = 6 \times EF$
Divide both sides by 6:
$EF = \frac{5.4}{6}$
$EF = 0.9$
The length of $EF$ is:
$$\boxed{0.9}$$
