D. 0.4y divided by 0.4 = 10 times 0.4

This is a multiple choice answer

Answer 1

`0.4y=10 \\ y=10 / 0.4 \\ y=25 \\ \\ A. \\ 0.4y=10 / 0.4 \\ 0.4y=25 \\ y=62.5 \\ y \\ot= 25 \\ \\ B. \\ 0.4y / 0.4=10 / 0.4 \\ y=25 \\ \\ C. \\ 0.4y * 2.5=10 * 2.5 \\ 0.4y=10 \\ y=25 \\ \\ D. \\ 0.4y / 0.4= 10 * 0.4 \\ y=4 \\ y \\ot=25`

The answer is B and C.
