Answer:
joseph = 11php/day
blouse = 319php
how many days will he sell?
lets represent days as A
11php multiplied with A days = 319php
11 x A = 319 (this is also the same as 11A = 319)
Divide both sides by 11 to get A.
A = 29, this is the number of days, Joseph needs to sell to buy the blouse
We can also use ratio and proportion
11 php = 1 day
319 php = ? days
11 = 319
1 ?
1 x 319 is 319
the product of 11 and ? should be = 319
so, 319/11 = 29
We can check by cross multiplication
29
x11
29
29
319
Therefore, 29 is correct.
