### Lance's Fraction Scribepost

#### 11. In a comedy review, each perfomer has a 1/4 slot. How many performers in a 2-h show.

The real question is how many groups of 1\4 are in 2. I estimated that the answer is going to be over 1 because the numerator 2 is bigger than the denominator 1\4. To figure out the answer you put 2\1 over 1/4 like this.

Then you do 1\4 x 4\1 which is called reciprocal. You do the same thing with the numerator so 2/1 x 4/1. The answer is 8/1 or 8.

Here is the pictorial form.

#### 13.Three quarters of a can of apple juice fills six glasses. How many glasses will a whole can of apple juice fill.

The real question is how many groups of 3/4 are in 6. I estimated that the answer is going to be over 1 because the numerator 6 is bigger than the denominator 3/4. To figure out the answer you put 6/1 over 3/4 like this.

Then you do 3/4 x 4\3 which is called reciprocal. You do the same thing with the numerator so 6/1 x 4/3. The answer is 24/3 or 8.

Here is the pictorial form.

#### 17. The average wind speed in Calgary is 4/5 of the average wind speed in Regina. The average wind speed in Calgary is 16km/h. What is the average wind speed in Regina.

The real question is how many groups of 4/5 are in 16. I estimated that the answer is going to be over 1 because the numerator 16 is bigger than the denominator 4/5. To figure out the answer you put 16/1 over 4/5 like this.

Then you do 4/5 x 5\4 which is called reciprocal. You do the same thing with the numerator so 16/1 x 5/4. The answer is 80/4 or 20.

Here is the pictorial form.

#### My Fraction Test Corrections

In a computer terminology, a bit is 1/8 of a byte. How many bits equal 16 bytes.
This is what i did.
The answer is 2 bytes

The right way to solve it is

So the real answer is 128 bytes
