53.5 =(5x10) + (3x1) + (5x1/10)50 + 3 + 5/10
0.53 =(0x1) + (5x1/10) + (3x1/100)0 + 5/10 + 3/100
he zero isn'treally necessary. that would be 2x1/10+5x1/100+3x1/1000 Thanks.
The Multiplicative Property of 1.
6x10+3x1+7x1/10
13.571 =(1x10) + (3x1) + (5x1/10) + (7x1/100) + (1x1/1000)10 + 3 + 5/10 + 7/100 + 1/1000
91.737 =(9x10) + (1x1) + (7x1/10) + (3x1/100) + (7x1/1000)90 + 1 + 7/10 + 3/100 + 7/1000
3x1=7 1+7=8 8x3=24
518.31 in expanded form = (5 x 100) + (1 x 10) + (8 x 1) . (3/10) + (1/100)
7.3005 =(7x1) + (3x1/10) + (0x1/100) + (0x1/1000) + (5x1/10000)7 + 3/10 + 0/100 + 0/1000 + 5/10000
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
