Use ratios, 20/15 = 25/x Multiply 15 by 20, then divide by 25. So 25 men could finish a job in 12 days.
-35
X/10 * 15/25 = 6 x=6
The answer is 27. 10+15=25. 25+2=27.
No
4 to 10 6 to 15 8 to 20 10 to 25
They are: 5 to 3
Ratio 3:2 (total 5), 25 / 5 = 5 per unit 3 * 5 = 15 2 * 5 = 10 ratio 15:10 (total 25)
2 is to 5 as 10 is to 25 the ratio 10/25 is the same as 2/5
10

15 - 25 = -10
35
It is -25 because -15--25 = 10
