Question

If you were solving 17 x 23 using the area model, which numbers would be partial products you would use to find the product

Answer 1

Answer:

The number to use are 10, 7, 20 and 3.

Step-by-step explanation:

Given

$17 * 23$

Required

Which numbers would be used using the area model or partial products

The number to use are 10, 7, 20 and 3.

This is shown below:

$\begin{array}{ccc}{ } & {10} & {7} & {20} & { } & { } \ \\ {3} & { } & { } \ \end{array}$

When the numbers are multiplied, we get:

$\begin{array}{cccc}{ } & {10} & {7} & {} & {20} & {200} &{140} &{=340}\ \\ {3} & {30 } & {21 } &{=51} \ \end{array}$

$Total = 340 + 51$

$Total = 391$
