3/8 of 1.28 = 3/8 x 1.28
= 3/8 x 128/100
= 3/8 x 32/25
= 96/200
= 12/25

Answer: B

1.28 * 3/8
= 128/100 * 3/8
= (2)^7/(5)^2(2)^2 * 3/(2)^3
= (2)^2/(5)^2 * 3
=12/25

Did an extra step but helped me keep organized.

.28/100 = 28 /100 reduced to 7 /25
1 = 25/25
25/25 + 7 /25 = 32/25
32/25 * 3/8 = 12/25

the reason for first reducing the .28 was to determine which common fraction to convert the unit of 1 to.
