The number is 84.Assign the digits in the number the letters a and b.GIVEN: a + b = 12GIVEN: a = 2bSolve for b, then solve for a.2b + b = 123b = 12b = 4a = 2(4) = 8

0.1 is 10% and 0.25 is 25%...Do you see a pattern? Your tenths place and hundredths place make up the first two digits of a percent. (in 0.25: 2 is the tenths and 5 is the hundredths) So if you have any digits after the hundredths place, they'll go after the decimal point in the percent. Ex. 0.5838 = 58.38% 1.904 = 190.4% Basically, you move the decimal point twice to the right and put a % at the end of it! ***for any further question email me at mrberry609@gmail.com
