Simplify 6y^4 / 9y

Step by step

The question

Question: simplify 6y⁴ over 9y.

1 Numbers and letters apart

We split it: numbers over numbers, and each letter over the same letter.

Fractions next to each other mean times.

2 Cross out

We write the powers out.

y⁴ is 4 y's on top.

y is 1 y's on the bottom.

y/y is 1.

Each y on top crosses out one y on the bottom.

1 pair crosses out.

3 y's are left on top.

The rule: same letter, divide, take away the powers.

6/9 is 2/3.

So we get 2y³ over 3.

Let's look back.

First: numbers and letters apart.

Last: cross out.
