SOLUTION
Given the question in the image, the following are the solution steps to convert to mg
STEP 1: Write the given kilogram

STEP 2: State the unit of conversion from kilogram to milligram
![1\operatorname{kg}=1000000mg]()
STEP 3: Convert the given kg to mg
![\begin{gathered} 1kg=1000000mg \\ \text{1}.35kg=y\text{ mg} \\ By\text{ cross multiplication,} \\ 1* y=1.35*1000000 \\ y=1350000 \\ 1.35\operatorname{kg}=1350000mg \end{gathered}]()
Hence, 1.35kg is equal to 1350000mg
