## anonymous one year ago At Priscilla's Purse Warehouse, it takes 2/3 of a day to complete 1/9 of an order of purses. At this rate, how long will it take to complete the entire order of purses?

1. Hero

Hint: (1/9)*9 = 1 order of purses

thx

3. Hero

@Maxipoo124, did you figure how how long it will take to complete the entire order?

4. anonymous

yes

5. Hero

How long will it take?

6. anonymous

13 1/2 days

7. Hero

What calculations did you use to come up with that result?

8. anonymous

2/3 x 9 cross multiplied

9. Hero

There's no cross multiplying involved in calculating (2/3)*9 ,

10. anonymous

well i multiplied 3 x 9 and divided it by 2 and got 13.5 but into a fraction its 13 1/2

11. Hero

You only cross multiply if you have a proportion: $\dfrac{a}{b} = \dfrac{c}{d}$ $ad = bc$

12. Hero

This is what you're multiplying: $\dfrac{2}{3} \times \dfrac{9}{1}$ You multiply the numerators first. Then the denominators

13. anonymous

so six days

14. Hero

Yes, correct.
