2. Write the numbers from their expanded form.

(1) [tex]$3,000 + 200 + 50 + 7 = 3257$[/tex]

(2) [tex]$10,000 + 5,000 + 1 = \square$[/tex]

(3) [tex]$4,000 + 500 + 10 + 3 = \square$[/tex]

(4) [tex]$20,000 + 300 + 40 + 5 = \square$[/tex]

(5) [tex]$7,000 + 80 + 3 = \square$[/tex]

(6) [tex]$90,000 + 90 + 2 = \square$[/tex]



Answer :

Sure! Let's write the numbers from their expanded form:

(1) [tex]\( 3,000 + 200 + 50 + 7 = 3257 \)[/tex]

(2) [tex]\( 10,000 + 5,000 + 1 = 15,001 \)[/tex]

The numbers add up as follows:
[tex]\[ 10,000 + 5,000 + 1 = 15,001 \][/tex]

(3) [tex]\( 4,000 + 500 + 10 + 3 = 4,513 \)[/tex]

Here,
[tex]\[ 4,000 + 500 + 10 + 3 = 4,513 \][/tex]

(4) [tex]\( 20,000 + 300 + 40 + 5 = 20,345 \)[/tex]

The expanded form results in:
[tex]\[ 20,000 + 300 + 40 + 5 = 20,345 \][/tex]

(5) [tex]\( 7,000 + 80 + 3 = 7,083 \)[/tex]

Simplifying,
[tex]\[ 7,000 + 80 + 3 = 7,083 \][/tex]

(6) [tex]\( 90,000 + 90 + 2 = 90,092 \)[/tex]

Adding the numbers,
[tex]\[ 90,000 + 90 + 2 = 90,092 \][/tex]

Thus, the filled-in numbers in their standard forms are:

(1) [tex]\( 3,257 \)[/tex]

(2) [tex]\( 15,001 \)[/tex]

(3) [tex]\( 4,513 \)[/tex]

(4) [tex]\( 20,345 \)[/tex]

(5) [tex]\( 7,083 \)[/tex]

(6) [tex]\( 90,092 \)[/tex]
