Front-end estimation is a particular way of rounding numbers to estimate sums and differences.
To use front- end estimation, add or subtract only the numbers in the greatest place value. Then add the decimals rounded to the nearest tenth.
Step-by-step explanation:
In front end estimation we are going to replace the original number with a number that is close by but only has one non zero digit. Examples: {20, 300, -50, 1,000, 80,000}. For example take the number 32, the choices to replace it with are 30 or 40 (they both have only one non-zero digit).
Answer:
I would say 135 would be the least three-digit number that is divisible by 3, 5, and 9.
Step-by-step explanation:
Some people don't consider 1 as a prime so
1,2,3,5,7,11
if you think 1 IS prime
1+2+3+5+7=18
if you think 1 IS NOT prime
2+3+5+7+11=23
it is either 18 or 23
I would consider 1 not prime and go with 23
Answer:

Step-by-step explanation:
1 5/6 + 1/2

11/6 + 3/6 = 25/6
14/6 equals 2 2/6 which simplifies to be 2 1/3 or 2 hrs, 20 min
