Answer 1

Answer:

Pls mark as brainliest if its helpful

Step-by-step explanation:

So, we will write it in the form of proportions:

400 gram : 1.2 mm :: 300 : x [ Let the extension produced be x]

{ We can see that more the weight more will be the extension. So, it is directly proportional}

[ we will use the formula

x: y :: a : b

x*b = a * y

]

400 x   = 300 * 1.2

x = 360/ 400

x = 0.9

Hence, there will be an extension of 0.9 mm.

Answer 2

Answer:

the corrects answer is 0.9 mm
