Question

Answer 1

She received 400 markers. 

To find this:
.1 x 4000 = 400

Answer 2

M.s. alonso ordered 4,000 markers for her store. Only 1/10 of them arrived

$\frac{1}{10}$ of markers arrived

Ordered markers = 4000

she received = $\frac{1}{10}$ of ordered marker

= $\frac{1}{10}$ * 4000 = $\frac{4000}{10}$= 400

So, M.s. alonso received 400 markers.
