Question

Answer 1

Answer

Find out the how many milliliters of sunscreen he needs to cover 325 cm² of the skin.

To prove

As given

Yoku Is putting on sunscreen.

He uses 2 ml of suncream to cover 50 cm² of his skin.

$2ml = 50 cm^{2}$

Now for 1 ml of suncream

$1ml = \frac{50}{2} cm^{2}$

1ml = 25 cm²

Thus for Yoku Is putting 1ml of sunscreen  to cover 25 cm² of his skin.

Let us assume that the  milliliters of sunscreen he needs to cover 325 cm² of the skin be x .

Now  Find out the  how many milliliters of sunscreen he needs to cover 325 cm² of the skin.

Than the equation becomes

25 × x =325

$x = \frac{325}{25}$

x = 13 milliliters .

Therefore 13 milliliters of sunscreen he needs to cover 325 cm² of the skin.

Answer 2

Alright so here it is

325/50=6.5
6.5*2=13
It would take 13 millimeters of sunscreen to cover 325 cm of skin
