Mikayla evaluated the expression 0.86 × 23.4 using the steps shown below.
Serga [27]

Answer:

Mikayla moved the decimal incorrectly.

Step-by-step explanation:

mikayla evaluated the expression 0.86 × 23.4 using the steps shown below.

0.86

× 23.4

344

2580

+ 17200

= 201.24

LEts do the multiplication without decimals

                    8 6

            x    2 3 4

          --------------------

                  3 4 4

              2 5 8 0

            1 7 2 0 0

------------------------------

             2 0 1 2 4

0.86 has two numbers after the decimal point and 23.4 has one number after the decimal point

So we move 3 places to the left ( 20.124)

Mikayla moved the decimal incorrectly.
