How to calculate percentage change

To compare two quantities and work out the percentage increase or decrease, follow these steps:

Step 1: Calculate the difference between the two quantities.

Subtract the initial quantity from the final quantity to find the difference. For example, if the temperature of a liquid started at 50° and increased to 60°, the difference is 10°.

Step 2: Divide the difference by the original quantity and multiply by 100.

To find the percentage increase or decrease, divide the difference by the original quantity and multiply by 100. If the difference is positive, it is a percentage increase, and if the difference is negative, it is a percentage decrease. For example, if the initial temperature is 50°, then the percentage increase would be:

Difference = 60° - 50° = 10°

Percentage increase = (10/50) x 100 = 20%

Therefore, the temperature increased by 20%.

So, to compare two quantities and work out the percentage increase or decrease, you need to calculate the difference between the two quantities, divide the difference by the original quantity, multiply by 100, and include the percent sign in the answer.

With our Cat and mouse math game you will be practicing the topic "Percentage change" from 8th grade / Number / Percentages / Percentages. The math in this game consists of 16 questions that ask you to compare two quantities to work out the percentage increase or decrease.

Move the cat to catch the white mice, hit the blue balloons, but avoid the red ones

Large thumbnail for math game Cat and mouse

Cat versus mouse game with added balloons for math and fun. You are the ginger cat, and your life is being made a misery by some white mice which have come into the house and are proving hard to catch. Not to mention there is a mouse house party going on and lots of balloons getting in the way of your hunting.

So you have to catch the white mice, forget about the gray mice, hit the blue balloons but avoid the red balloons, and answer math questions (you are a CLEVER cat...). If it sounds complicated and a bit frantic, that's because it is. Do your best but don't worry if you can't catch all the mice - neither can we. It's a cat's life...

Free Math Games screenshot of the CAT AND MOUSE game for secondary

CAT AND MOUSE is a quirky take on the perennial enmity of ponderous predator and plucky prey. Here are the basics:

  1. Press "PLAY" on the CAT AND MOUSE settings page to open the game.
  2. You are a ginger cat overwhelmed by a serious mouse problem.
  3. Luckily your job is only to catch the white mice, not all the mice.
  4. Trouble is, they are not easy to catch and will try to avoid you.
  5. Use the arrow keys or tap the screen in the direction you want the cat to go.
  6. You will need fast reaction times to catch those white mice, and the balloons keep getting in the way.
  7. Mouse scores are 25 points for each white mouse caught, minus 5 points for each white mouse that escapes.
  8. When you do catch a white mouse, a math question will appear.
  9. Answer the math question correctly for those extra points...
  10. You get 50 points for each correct answer, but you lose 25 points for each wrong answer.
  11. Hitting blue balloons gives you extra points, but 3 hits on a balloon will burst it for that level.
  12. Hitting red balloons takes away points.
  13. Balloon scores are +5 or +10 points for blue balloons, -5 or -10 points for red balloons.
  14. This is a timed game and your final score is calculated by taking away your time in seconds from the points you have earned.
  15. If you get one of the 10 best scores you can add your name to the leaderboard for your chosen topic.
