Answer 2

Answer:

let the left flour =x.

lost flour is 2/5 of the total.

so x will be total flour - lost flour.

so 12 1/2 kg = 25/2kg.

now to find the left we will multiply 2/5 × 25/2 as 2/5of 25/2 was lost.

2/5×25/2

=>its 5 kg.

lost flour is 5kg so

left flour is original-lost.

25/2kg - 5kg.

so now take out the LCM.

lcm=2

so left flour is 15/2kg or 7.5 kg

Step-by-step explanation:

so the answer is 7.5 kg is left in it
