Answer 1

The correct option is C $(7\times 1)+(5\times \frac{1}{10})$

Let's write 7.5 in a place value chart.


With the help of this place value chart, let's write the number in an expanded form.

Multiplying each face value with its place value, we get:

$⟹7.5=(7\times 1)+(5\times \frac{1}{10})$
