I think that 10 is 20% of 50
758 rounded to the nearest hundred would be 800 because the five would round the seven up.
a. 2⁄5 = 0.4 = 40%
b. 7⁄20 = 0.35 = 35%
c. 11 1⁄16 = 6.9375 ≈694%
d. 141⁄4 = 35.25 = 3525%
open the parenthes. and then after that you'll get 27+12x-15. if you simplify that then you'll get 12x+12
