Question

Use mental math to solve 3x1,607

Answer 1

Answer:

The product is 4,821

Step-by-step explanation:

We are given the following information in the question:

We have to multiply an expression using mental maths.

We can expand the numbers and use the distributive property to do so.

• The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
• It help us to perform complex multiplication problem easily.
• $a\times(b+c) = (a\times b) + (a\times c)$

The solving is shown below:

$3\times (1607)\\=3\times (1000 + 600 + 7)\\=(3\times 1000) + (3\times 600) + (3\times 7)\\=3000 + 1800 + 21\\=4821$

The product is 4,821
