@MissSmartiez

OpenStudy (misssmartiez):

1,000 x _ = 2,900

OpenStudy (anonymous):

1. cross multiply : 1000*x = 2900*1 x = 2900/1000 x = 29/10

OpenStudy (anonymous):

you can use the same hint for questions 6 and 7

OpenStudy (misssmartiez):

1,000 x 2.9 = 2900|dw:1457468796840:dw|

OpenStudy (misssmartiez):

so, 5: B

OpenStudy (misssmartiez):

Next.

OpenStudy (misssmartiez):

100 x 7.2 = 720.1 x ? = 720. Mental math. 1 x y would always equal y. So 720.

OpenStudy (misssmartiez):

6: D

OpenStudy (anonymous):

I very stuck on the last one @MissSmartiez

OpenStudy (misssmartiez):

7: 1 kg = 1000 grams.

OpenStudy (misssmartiez):

So, 22 of those x 1,000 is?
