Answer:
Step-by-step explanation:
Rayna wrote 260,980 as
(2 × 100,000) + (6 × 1000) + (9 × 1000) + (8 × 100)
Since 2 is at 100 thousand place so 2 × 100,000 is correct.
6 is at 10 thousand place so 6 × 10000 is correct.
9 is at hundreds place so it should be (9 × 100) in place of ( 9 × 1000) so this step is wrong.
Similarly 8 is at tenth place so it will be (8 × 10) in place of ( 8 × 100) so this step is also wrong.
So Rayna made error in writting ( 9 × 1000 ) and ( 8 × 100 ).
