Help with decimals please? 10points

.45 in fraction

please explain step by step

thanks

.45 = 45/100 = 9/20

basically you see that there are two numbers behind the decimal point, so that means the bottom number (denominator) will be 100 (a one with TWO zeroes) you will always have a number start off over 10, 100, 1000, and so on in these case. So since there are two numbers, use the number with 2 zeroes (100)
45 was your original number so that is the top number (numerator)

45/100

divide by common factors to make it simpler
45/5 is 9
100/5 is 20
simplest term 9/20

its quite simple.

When there is only 1 number like .4 it will always be out of /10 no matter what. so its 4/10 its like 40%

When the Number is 2 numbers long. .45 it will always be out of 100 no matter what. so it would be 45/100

.73 it would be 73/100

.5 it would be 5/10

sorry if i didn't explain very well. Its just so simple, it doesn't need to much explaining :3

0.45= 45/100 decimals are read by the "point" and places. you just have to learn this it's not a matter of trying to find some neat mathematical principle. 0.5= 5/10 or 1/2 reduced.study you'll need this info .

.45 is an easy decimal to fraction. all u have to do is drop the decimal, and make the fraction 45/100. then reduce to 9/20. so ur final answer is 9/20.

.45 means forty five hundredths.
45/100
reduce by 5
9/20

0.45 is the same as 45/100
reduce this (divide both numerator and denominator by 5) we get 9/20

9/20

=>.45
= 45/100
= 9/20
