1. 5:15 = 1/3
scale factor is 1/3going from bigger to smaller
2. 2/8 = 1/4
14 x 1/4 = 3.5
X = 3.5
Answer and Step-by-step explanation:
If you see a number or fraction or anything we g beside it, such as:
4.2g
6g

^ That is grams
If you see anything with kg next to a number, fraction, e.t.c, such as

5kg
6.2kg
^ That is kilograms
24- sqrt(720/4) divide 720 by 4
24 - sqrt (180) now break down 180 to 9*4*5
24- sqrt(9) *sqrt(4) *sqrt (5) so 9becomes 3, 4 becomes 2
24- 3*2*sqrt(5) multiply 3 and 2
24-6sqrt(5)
Start with the parentheses
