Save trees

25 tons of old paper will save 1,600 trees. How many tons of paper is needed to save the 32 trees in the park?

Correct result:

x =  0.5 t

Solution:

x=321600 25=12=0.5 tx=\dfrac{ 32 }{ 1600 } \cdot \ 25=\dfrac{ 1 }{ 2 }=0.5 \ \text{t}



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
