Final answer:
The numbers 0.98 and 0.980 are equivalent because adding a zero to the end of a decimal number does not change its value.
Step-by-step explanation:
When comparing the numbers 0.98 and 0.980, it is important to understand that adding a zero at the end of a decimal does not change its value. Therefore, 0.98 and 0.980 are equivalent. Both numbers start with a 9 in the tenths place, followed by an 8 in the hundredths place. The additional zero in 0.980 does not contribute any value since there are no non-zero digits following it. So, 0.98 is equal to 0.980.
