Question 1Easier
A route is 64,508 meters long. Rounded to the nearest thousand meters, what is the length of the route?
Show answer
Answer: D — 65,000
The hundreds digit is 5, so 64,508 rounds up from 64,000 to 65,000.

What this topic is
Estimation questions reward rounding sensibly rather than computing exactly.
Typical items ask for a value rounded to a given place, an approximate quotient, or a reasonable average of a few nearby measurements. Rounding to the nearest thousand means looking at the hundreds digit: a hundreds digit of five or more rounds up, and anything smaller rounds down. For division, replacing both numbers with compatible values, such as four thousand divided by eighty, gives a quick answer of fifty.
SSAT Upper answer choices are usually spread far enough apart that a careful estimate picks out one of them, while an exact calculation wastes time on a timed section.
Sample questions
Pick an answer to see whether it is right — nothing is saved, and nothing needs an account.
Question 2Easier
At a factory, Maya uses a machine to divide 4,118 parts equally among 82 batches. About how many parts are in one batch?
Show answer
Answer: A — 50
Use the compatible numbers 4,100 and 82. Since , each batch has about 50 parts.
Question 3Easier
Wind speeds over four intervals were 18, 21, 23, and 19 miles per hour.
Which of the following is the best estimate of the mean wind speed?
Show answer
Answer: B — 20 miles per hour
The four speeds cluster near 20. Their total is about 80, and miles per hour.
