Part b) Number entry

Gap-fill

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

$\var{a1}$ to $\var{n1}$ decimal place = Gap 0.

$\var{a2}$ to $\var{n2}$ decimal places = Gap 1.

$\var{a3}$ to $\var{n3}$ decimal places = Gap 2.

Advice

1. As the second decimal place for {a1} is {grorle} we {incorleave} the first decimal place and the answer is {dpformat(ans1,1)} to 1 decimal place.

{mes}

2. The third decimal place of {a2} is {grorle1} and so we {incorleave1} the second decimal place and the answer is {dpformat(ans2,2)} to 2 decimal places.

{mes1}

3. The fourth decimal place of {a3} is {grorle2} and so we {incorleave2} the third decimal place and the answer is {dpformat(ans3,3)} to 3 decimal places.

{mes2}
