Is 202 hundredths equal to 2 hundreds and 2 thousandths
Murljashka [212]

Answer:

No

Step-by-step explanation:

202 hundredths is equivalent to 0.202.

Starting from left, 0 is in unit place, 2 is in Tenths place, 0 is in Hundredths place and 2 is in thousandths place.

The value of 2 (at left, just after decimal) is 1/10

The value of 2 (at right,) is 1/1000

It means, 202 hundredths is equal to 2 tenths and 2 thousandths. Hence, the given statement is not correct.
