Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Round the following decimals to the nearest whole number (0 decimal places):

{wholelist[0]}=Gap 0.

{wholelist[1]}=Gap 1.

{wholelist[2]}=Gap 2.

Advice

Steps to follow:

1. Retain the correct number of decimal places (e.g. 3 for thousandths, 0 for whole numbers)
2. If the next decimal place value is 5 or more, increase the value in the last retained decimal place by 1

Example-

134.9 rounded to tens is 130 as the next digit (4) is less than 5

12,690 rounded to thousands is 13,000 as the next digit (6) is 5 or more

15.239 rounded to units is 15 as the next digit (2) is less than 5
