Step-by-step explanation:

To determine the total amount of meat Yolly has, we need to add the weights of the chicken and beef together.

Yolly has 1/² kilograms of chicken, which can also be written as 1/2 kilograms.

Yolly also has 49.57/4 kilograms of beef.

To find the total amount of meat, we add these quantities:

1/2 + 49.57/4

To simplify this, we need to find a common denominator. The denominator for 2 and 4 is 4. Therefore, we can rewrite 1/2 as 2/4:

2/4 + 49.57/4

Now we can add the numerators together:

(2 + 49.57) / 4

This gives us:

51.57 / 4

To evaluate this division, we divide the numerator by the denominator:

51.57 / 4 ≈ 12.8925

Therefore, Yolly has approximately 12.8925 kilograms of meat in total.
