Reading/ordering numbers

Worked solution

1. 1

   Compare the hundreds.

   $300<800$

   Both $308$ and $380$ have three hundreds; $803$ has eight, so it is largest.

2. 2

   Compare the tens in the two smaller numbers.

   $0<80$

   The hundreds match, but $308$ has no tens and $380$ has eight tens.

3. 3

   Write the numbers in increasing order.

   $308<380<803$

   The comparison of hundreds and then tens decides their order.

Worked solution

1. 1

   Split the number into its places.

   $605=600+0+5$

   The digits show six hundreds, no tens and five ones.

2. 2

   Read the hundreds and ones together.

   Say “six hundred and five”; the empty tens place adds no tens word.
