who's answer is right i will mark as brainlist ​

Answer 1

Answer:

Weight of first part = 1 kg

Weight of second part = 0.8 kg

Step-by-step explanation:

Let the second part be x.

Given, First part was 25% heavier than the second part.

First part = x + 25% of x

Given, the pizza weights 1.8 kg      

x + (x + 25% of x) = 1.8    

=> x + (x + 25x/100) = 1.8

=> x + x + 25x/100 = 1.8

=> 2x + x/4 = 1.8

=> 9x = 7.2

=> x = 0.8

Then,

First part = 1.8 - x = 1 kg

Therefore,

Weight of first part = 1 kg

Weight of second part = 0.8 kg

Answer 2

Answer:

0.8 and 1 kg

Step-by-step explanation:

Let the second part of pizza be x kg

Then, first part = x + 25% of x

Now, total weight ⚖️ of pizza = 1.8 kg (Given)

x + (x + 25% of x) = 1.8 kg

x + (x + x/4) = 1.8 kg

2x + x/4 = 1.8 kg

9x/4 = 1.8 kg

9x = 7.2

x = 0.8 kg.

Thus, first part of pizza will be = 1.8 - 0.8 i.e., 1 kg
