Question

1/4 + 23/28 - 1 please help

Answer 1

Answer:

$\frac{1}{14}$

Step-by-step explanation:

$\frac{1}{4} + \frac{23}{28} - 1 = ?$

First off, let's change everything to a common denominator. This will allow us to add the fractions!

To find a common denominator, we find a number that both 4, 28, and 1 can go into. 28 is the best choice, as 4 goes into it 7 times, 28 goes into it once, and 1 goes into it 28 times.

Let's change the first fraction into a number with a denominator of 28!

$\frac{1}{4} * \frac{7}{7} = \frac{7}{28}$

$\frac{7}{7}$ = 1. Multiplying a number by one doesn't change its value.

The second fraction, $\frac{23}{28}$, already has a denominator of 28, so we don't have to do anything with it.

Now to the third number, -1:

$-1 = -\frac{1}{1} * \frac{28}{28} = -\frac{28}{28}$

Now, let's add them all up!

$\frac{7}{28} + \frac{23}{28} - \frac{28}{28} = \frac{7 + 23 - 28}{28} = \frac{2}{28}$

One last step, to simplify:

$\frac{2}{28} = \frac{1}{14}$

Your answer is 1/14!
