It takes 20 men 60 days to complete a building work. How many days longer will It take 15 men, assuming they work all work at the same rate?

80days

Step-by-step explanation:

20m=60days

15m(will take more days)

20÷15×60 = 80 days

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
