Aisha changed 1.45 + 2.38 to 1.5 + 2.4 in order to estimate the sum. What estimation method did she use?

Mercury:

next time please post the answer choices - front-end clustering - rounding to the nearest tenth - rounding to the nearest hundredth

Mercury:

that being said, any thoughts on this one? notice how they rounded 1.45 to 1.5 and 2.38 to 2.4 so they rounded to the digit right after the decimal point. is this the tenths place, or the hundredths place?
