oee [108]

Answer:

In the step-by-step explanation!

Step-by-step explanation:

Not sure if it is too late but here:

1.)

$\frac{1}{\alpha}+\frac{1}{\beta} \\\frac{\beta}{\alpha \beta } +\frac{\alpha}{\alpha \beta } \\\frac{\alpha +\beta }{\alpha \beta }$

2.)

$\frac{1 }{\alpha } *\frac{1}{\beta} = \frac{1*1}{\alpha*\beta} =\frac{1}{\alpha \beta}$

3.)

$\frac{1}{\alpha}-\frac{1}{\beta}\\ \frac{\beta}{\alpha \beta } -\frac{\alpha }{\alpha \beta } \\\frac{\beta -\alpha }{\alpha \beta }$

Hopes this help! Please give me Brainliest!

Of the 100 donated gift baskets, you raffled off 97. What fraction of the baskets are left?

Nesterboy [21]

There are 100 baskets in total. 97 were raffled off. This means you'll want to subtract 97 from 100.

Let's turn those numbers into an equation:

100/100 - 97/100 = ?

100 - 97 = 3

So, ? = 3/100

3/100 cannot be simplified.
