Which number produces a irrational number when added 0.25
Helen [10]
I think the easiest way to think about this is to put 0.25 into fractional form. 0.25 = 1/4 because 4 divided into 1 = 0.25

So 1/4 added to 2/9 will give us a fraction (rational number). Of course to determine what the fraction is, we have to get a common denominator.
(In case you wanted to know what that rational number is: The least common denominator would be 36. So changing 1/4 by multiplying top and bottom by 9 gives 9/36 and changing 2/9 by multiplying top and bottom by 4/4 gives 8/36 and adding 9/36 to 8/36 gives 17/36 - a rational number.)

On the first day camping, a group hiked at a rate of 2 1/4 miles per hour for 2 1/2 hours before taking a break. How many miles
DaniilM [7]

First, use the distributive property and split 2 off from 1/2 in the hours category.

(2) (1/2)

Next, multiply 2 1/4 times 2, the first integer in the distributive equation.

2 1/4*2 = 4 1/2

For now, put 4 1/2 aside.

Then, multiply 2 1/4 by 1/2.

2 1/4*1/2 = 1 1/8

Now, add the two products together

4 1/2 + 1 1/8 = 5 5/8

Answer is 5 and 5/8

Hope this helps!
