Question

Choose the correct representation of the first step of the lattice method when solving the multiplication of 135 by 46.

• A.
• B.
• C.

Answer 1

The correct option is B

• To find out the value of $135\times 64$ using the lattice method, we have to split $135$ into it's digits as $1$, $3$ and $5$, and write sequentially on top of the table from left to right.

• Whereas, we have to split $64$ into it's digits as $6$ and $4$, and write on right of the table from top to down.

Hence, the below figure is the correct initial representation for solving $135\times 64$ using the lattice method.


$\therefore$ Option (b.) is the correct one.
