Question

Choose the correct initial representation for solving $137\times 45$ using the lattice method.

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

To find out the value of $137\times 45$ using the lattice method, we need to split $137$ into $1$, $3$ and $7$, and need to write sequentially along the table from left to right. Whereas, we need to split $45$ into $4$ and $5$, and need to write accross the table from top to down.

Hence, the below figure is the correct initial representation for solving $137\times 45$ using the lattice method.


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