Activity 6

What is 370.76 grams in kilograms? There are 1000 grams in a kilogram.

Answer

370.76 ÷ 1000 = 0.370 76.

So 370.76 g = 0.370 76 kg.

Activity 7

Place the following numbers of kilometres in order, with the smallest distance first:

  1.013   1.103   1.0103   1.0129

Answer

Writing the numbers out in columns with the decimal points lined up (as in a place value table), gives:

1.013

1.103

1.0103

1.0129

Working from the left shows that 1.0103 is the smallest, follwed by 1.0129. So in ascending order they are: 1.0103,  1.0129,  1.013,  1.103.

Activity 8

Place the following measurements in ascending order:

0.1704 metres   0.1074 metres   0.0714 metres   0.0741 metres

Answer

Writing the numbers out in columns with the decimal points lined up (as in a place value table), gives:

0.1704

0.1074

0.0714

0.0741

Working from the left, shows that 0.0714 is the smallest, followed by 0.0741. So in ascending order (in metres) they are:

  0.0714,  0.0741,  0.1074,  0.1704.
