Using exponents, 1 trillion in expanded notation is:
(1 x 1012) + (0 x 1011) + (0 x 1010) + (0 x 109) + (0 x 108) + (0 x 107) + (0 x 106) + (0 x 105) + (0 x 104) + (0 x 103) + (0 x 102) + (0 x 101) + (0 x 100).
1 trillion = 1,000,000,000,000
1.7 = 1*100 + 7*10-1
1.25 in expanded form is (1 x 1) + (2/10) + (5/100)
1 + 0.6
7 + .1
1 trillion = 1,000,000,000,000
Oh honey, it's not rocket science. To write 21.5 in expanded form, you simply break it down into its different place values. So, 21 is 20 + 1, and 0.5 is just 5 tenths. Put it all together and you get 20 + 1 + 0.5. Ta-da!
1.7 = 1*100 + 7*10-1
Not sure where Google comes into it, but the expanded form is 1 + 0.7
1.29 in expanded form = (1 x 1) + (2/10) + (9/100)
