Make a fraction division equation
guajiro [1.7K]
Hey there!
Let's make one and solve it.
Fraction division is solved by using a simple rule:
"keep, switch, flip!"

So if we have:
4/8 divided by 5/9

We keep the 4/8, switch the division to multiplication, and flip the 5/9 to 9/5:

4/8 * 9/5 = 36/40 = 18/20 = 9/10

Hope this helps!

The table shows a relation between x and y.<br><br> is the relation a function, and why?
notsponge [240]
<h2>Function Definition</h2>

A function is a relation in which there is only one y-value for every x-value.

If we given an input of 3 for x, for example, we would only get one output for y, like 1, for example.

<h2>Answer</h2>

If we look at the table, we can see that the x-value of 3 gives us two outputs: 7 and 9.

Therefore, this relation is not a function.
