Question

3. If 15 men can do a work in 12 days, how many men will do the same work in 6 days? please given me answers ​

Answer 1

Answer:

The answer is 7.5

As the number of days is halved

Answer 2

Answer:

7.5 men can do the work in 6 days (.5 is like 1 person working for 3 days that is for half days)

Explanation:

We use ratios to solve the problem:

$15:12 = x:6$

Now we multiply the means and extremes:

$15$ x $6 = 12x$

$90 = 12x\\\frac{90}{12} = x\\7.5 = x$
