The answer is 3. Would you like me to explain it?
NUMBER 3 :
150 feet / 15 = 10 units
120 feet / 15 = 8 units
So it will be 10 units by 8 units
NUMBER 4:
A) 525/4.2 = 120
The scale used was 120
B) 0.6 inches = 0.0152
525 / 0.0152 = 35 sheets tall
Well its a simplest form of zero and 6 tenths and if u divide it by 2 youll get 3/5 as a fraction
