20% because there are 10 numbers and 2 of them are a multiple of 5. :)
72 + 12x = 24 + 24x
48 = 12x
4 = x
It‘ll take 4 years.
X and 1 are common factors eh
Okay so, I am assuming the model is smaller so it would be 0.34m long.
The model has to be 200 times smaller than the actual plane
Divide 68/200 and you get 0.34
Then to check your answer, multiply 0.34 by 200 which is 68 meaning
0.34:68 is equal to 1:200
Assuming the model is bigger (just in case) it would be 13,600m long.
The in this scenario, the model has to be 200 times bigger so it would be 68(200) which is 13,600
Hope this helps
