corina multiplied 62 and 22 got a product of 1,042. explain why Corina's answer is not reasonable?

Question

Multiplying 2-digit number

Answer 1

20*60=1200

so 22*62 gotta be > 1200

Answer 2

Corina's answer is wrong because she multiplied wrong. So i'm not gonna give you the answer but,first you multiply 2x2 which equals 4. then you multiply 6x2 which equals 12. So you drag the 1 on top and drop the 2.then you have to figure out what to do next. once you have your answer, add them all up.then you will have         .

Comments

Wrong. You are supposed to do 2x2=4. Then you do 6x2. Instead of putting the 1 on top and the two on the bottom you write the 12 entirely. That's the way math works.

Answer 3

62< 22

60< 20

WHAT YOU DO IS PUT 62 TIMES 22 AND ROUND THE 62 TO A 60 AND 22 TO A 20.THAN MULTIPLY 60 TIMES 20 AND IT WILL EQUAL 1,200.HERE IS AN EXAMPLE HOW SHE DID THIS EQUATION WRONG.

1. EX. 62< 22
2. 60< 20
3. [ 1,200]
