Jane multiplied 825 x 22 and got 3,300. Flynn multiplied the same numbers and got 18,150. Which student is correct? What mistake did the other student make?
Answer:
Flynn got the right answer.
\(825\times 22 = 18150\)
Step-by-step explanation:
We are given two persons Jane and Flynn. They carried out multiplication of two same numbers but got different product.
We need to check who performed the correct calculation.
\(825\times 22\)
Jane received an answer of 3,300 and Flynn got an answer of 18,150.
The right product is:
\(825\times 22\\=825\times(20+2)\\=16500 + 1650\\=18150\)
Thus, Flynn got the right answer.
Jane got the wrong answer. Maybe she copied down the wrong numbers. Jane multiplied 825 by 4 instead of 22.\(825\times 4 = 3300\)
