Question

847 × 3 =(800 x 3) (40 x3 ) (7 x 3) =2,400 1,200 21 =3,621 where is the error

Answer 1

Explanation:

In the given expression, "847 × 3," the error is in the multiplication steps:

1. You correctly broke down 847 into its place value components: 800, 40, and 7.

2. You then correctly multiplied each component by 3.

The error is in the addition step:

You added the results incorrectly:

2,400 (800 x 3)

1,200 (40 x 3)

21 (7 x 3)

The correct addition should be:

2,400 (800 x 3)

120 (40 x 3)

21 (7 x 3)

Now, adding these correctly:

2,400 + 120 + 21 = 2,541

So, the correct result for 847 × 3 is 2,541, not 3,621. The error occurred during the addition step.
