Answer:

about 6.9 cm

Step-by-step explanation:

Set up a proportion to solve this problem.

1 cm is to 6.5 miles as x cm is to 45 miles

1/6.5 = x/45           now solve for x by cross multiplying

45 = 6.5x

45/6.5 = x    

  6.923076923 cm = x

Divide. Reduce the answer to lowest terms 2 1/9 ÷ 3 1/3
aleksandrvk [35]

Answer:

I am pretty sure the answer is 19/30

Step-by-step explanation:

If u turn 2 1/9 ÷ 3 1/3 into improper fractions u will get 19/9 Divided by 10/3

Then u do the butterfly. So this would be 9 x 10 =90 and 19 x 3 =57 so this is what it looks like 57/90 and that can be simpflyed into 19/30. Becasue 3 x 19 = 57 and 3 x 30 = 90
