Can someone tell me if I did this right? 1. Given: the standard representation 753864293
Write the expanded representation of this number.
My 7 hundred million, 5 tens millions, 3 million, 8 hundred thousand, 6 thousand, 4 thousand. 9 tens, 3 ones

2. Given: the expanded representation
7·1 + 5·100 + 3·1000 + 8·1000000
Write the standard representation of this number.
My 7·1 + 5·100 + 3·1000 + 8·1000000
7·1=7 5·100=500 3·1000=3000
8·1000000=8000000
and adding the numbers: 7+500+3000+8000000=8003507

3. Given: the standard representation 1010111000
Write the expanded representation of this number.
My 1 billion, o hundred million, 1 ten million, 0 million, 1 hundred thousand,1 tens thousands, 1 thousand, 0 hundred, 0 tens, 0 ones

4. Given: the expanded representation
1 ·1 + 0 ·2 + 1 ·16 + 1·128
Write the standard binary representation of this number.
my 1 ·1 + 0 ·2 + 1 ·16 + 1·128
1 ·1 + 0 ·2 + 1 ·16 + 1·128
1 ·1=1
=1+0·2+1·16+1·128
0·2=0
=1+0+1·16+1·128
1·16=16
=1+0+16+128
1·128=128
=1+0+16+128
1+0=1
=1+16+128
1+16=17
=17+128
17+128=145
final 145
