Well, the greatest common factor of both 24, and 60 is 12. 24 ÷ 12 =2, while 60 ÷ 12 is 5, so the new fraction is 2/5.
The reason I divided the numerator and the denominator by the same number is because you are basically dividing by 1(12/12=1). Anything divided by 1 is itself.
Answer:
{x : x ε Z where x<3 & x>4}
For the middle square: 20in x 20in= 400in
For ONE flap: 20in x 12in= 240in
Multiply by 4 to get the area of all the flaps: 240in x 4 flaps= 960in^2
Add: 400+960= 1360in^2
It would be y=3x+5. This is because if it is going at a rate of 3cm a month, this makes it the constant value or the slope. But since it’s starting value is 5cm, that would make it the y-intercept, which is why your answer would be y=3x+5.
