1/5 of a metre. 0.2m. 20cm. However you like to write it :)
This is because 3/5 is being divided by 3. So a third of 3/5 is 1/5, just as a third of 3 is 1.
Also, if you change it decimals, you get 0.6m ÷ 3 = 0.2m. You can then change it to cm if you like. 0.2m, 20cm, 1/5 of a metre. They're all the same thing and equally acceptable as an answer.
Hope I helped :)
Answer:
Go for the 200 copies!
Step-by-step explanation:
Paying 77 times $0.39 is $30.03, which is more than the 200 copies offer, so even if you throw away all the copies you don't need, the 200 offer is still cheaper!
Is that Chole and Dave <em>each </em>get 2.5 times Ann? Let's assume so.
A:B=2 : 9
A:C:D=1 : 2.5 : 2.5
We can scale ratios without changing them, like fractions.
A:C:D=2:5:5
With A the same in both ratios we can put them together.
A:B:C:D=2:9:5:5
There's some scale factor k such that
k(2+9+5+5)=399
k = 399/21 = 19

Answer:
x=13.7
Step-by-step explanation:
CD=CB=6
AC=AD+CD => AC=9+6 => AC=15
AC^2= AB^2 + BC^2 => 15^2 = X^2 + 6^2 => 225 = X^2 + 36 => X^2 = 225 - 36 => X^2 = 189 => X=13.7
