Step-by-step explanation:
Below are the steps to divide fractions:
- The 1st fraction remains untouched.
- The division sign turns into a multiplication sign.
- Flip the 2nd fraction over (finding its reciprocal)
- Multiply the numerators (top numbers) together
- Multiply the denominators (bottom numbers) together.
- Simplify the resulting fraction by dividing both numerator and denominator by the same number.
Let's follow the above steps:
Steps 1, 2 and 3 can be done together.
As you can see, we leave 1st fraction alone, change division sign (:) by multiplication sign (.), and flip 2nd fraction over.
Now, we can do steps 4 and 5...
Finally, step 6, we cannot simplify the resulting fraction since both numerator and denominator have no common factors.
9 = 3 . 3
10 = 2 . 5

Step one is to find the total area of the slab of wood before any cuts are made. What's the formula to find the area of a rectangle? base*height. The square is 18 long and 18 high, so to find the area you'd need to do 18*18, and you should get 324 inches^2 as the area of the square.
Step two is to find the area of a triangle. How can you find the area of a triangle? Well, think of it this way... What do you get when you cut a square in half, diagonally? A triangle! So if the formula for the area of a square is A=bh (base*height), then wouldn't the formula of a triangle be 1/2(bh), since a triangle is half of a square? Yep! So what would be the area of this triangle? It would be 1/2(6*4), because the base is 6 and the height is 4. 6*4 is 24, so now you have 1/2*24. One half of 24 is 12, so the area of the triangle he uses is 12.
Step 3: If he uses that wood, doesn't that mean he's taking it away? What's another word for "take away"? Subtract! That means you subtract the triangle he uses from the square he cut it out from! If the area of the square slab of wood is 324, and you subtract 12, 324 -12 is 312! That means that the area of wood he will have left over is 312 inches ^2! I hope this was helpful!
