1. Five workers take 12 days to weed a
field. How many days would 6 workers
take ? How many would 15 take ?​

Answer 1

Step-by-step explanation:

ANSWER

1st part

We have,

Worker W1 =5

Weed a field in days D1 = 12days

If,

Take worker W2 = 6

Then, Days D2 = ?

Then, we know that,

W1 D1 = W2 D2

5×12=6×D2

D2 = 5 × 12 / 6

D2 = 10 days

2nd part,

If workers W3 = 15

Then,

Days D2 =?

Then, we know that,

W1 D1 = W3 D3

5×12 = 15×D3

D3 = 5×12/15

D3 =4days

Hence, this is the answer.
