Write o.45 repeating as a fraction in lowest terms

0.45 as a fraction.

As this fraction is rounded to the hundredths, simply put 45 as the numerator, and 100 as the denominator.

45/100

However, this is not the simplest (lowest) form, so we must simplify this.

Divide both the numerator (top number) and the denominator (bottom number) by 5.

45 ÷ 5 = 9

100 ÷ 5 = 20

So, we now have 9/20

That is the simplest it can be.

~Hope I helped!~

.45 as a fraction would be 9/20 because first you would do 45/100 and then divide by 5 because thats the highest number that can go into 45 and 100. so the simplified fraction would be 9/20. 

Chance of getting number greater than 4 on one roll:

Either getting a 5 or 6

2/6 probability

2/6 = 1/3

If we roll the cube 12 times, the probability of getting a number greater than 4 is 1/3 of the time

12 * 1/3 = 4

She is expected to get a number greater than 4, 4 times
