Is 0.7 =0.07 reasonable? explain why if its not or it is
MrRissso [65]

Answer:

No

Step-by-step explanation:

No, because 0.7 is greater than 0.07 {Tip: Look for place of the decimal}

0.7 is written as 7/10 and 0.07 is written as 7/100

0.7 which is 7/10 is also written as 70/100 Hence, it clearly that 70/100 is greater than 7/100

0.7 is greater than 0.07 because to compare between two decimal numbers, you should look at the number after the decimal point and 7 is greater than 0 in the tenth place.
