4 and 2/5 as a decimal is 4.4
0.753/4:= 3 ÷ 4= 0.75 in decimal
In bar notation, it is .42. The bar rests atop the 42.
decimal notation for 17/4= 4.2517/4:= 17 ÷ 4= 4.25 in decimal
decimal notation for 4 3/10 = 4.30
4 tenths i decimal = 0.4
To change for percent to fraction, move the decimal over 2 places to the left. You need to put a decimal place after the 4 in 234, so it is really 234.0. Now when you move it over 2 places to the left you have 2.34.This is the answer.
Scientific notation is written like this: (number) * 10(exponent)Scientific notation is written by moving the decimal point over until there is only one digit in front of it. The number of times you have to move the decimal over is the exponent you use.Example: 786,450,000.0 --> Move the decimal over 8 times = 7.8645Answer: 7.8645 * 108If the number is a decimal, you do the same thing, but write a negative exponent instead of a positive.Example: 0.0004687219 --> Move the decimal over 4 times = 4.697219Answer: 4.697219 * 10-4
4/100 as a decimal is 0.04
It is: 4/2 = 2/1 = 2.0 as a decimal but 2/4 = 1/2 = 0.5 as a decimal
2 and 4 over 25 in decimal form = 4.16 2 4/25 = 2 + (4 ÷ 25) = 4 + 0.16 = 4.16
When using scientific notation, you shift the decimal place over until there is only one digit in front of the decimal place and count how many times the decimal moved. 55,000 would be 5.5x10^4 because the decimal moved over four spots to the left. If the number was .00055 then the answer would've been 5.5x10^-4 because the decimal moved 4 places to the right.
equivalent decimal for 4 and 2 over 25 = 4.084 2/25= 4 + (2 ÷ 25)= 4 + 0.08= 4.08
