Maths Quiz for Kids

Answer: 14

6+x=20, so x=20-6=14
This is an example of algebra. There will be more of a challenge in the next few questions.

Answer: 75

75: add 10, subtract 5 and then divide 2, my answer is 40. Use inversion (work backwards using the operations given) for these types of questions!

Answer: 16

The sequence is: 1, 4, 7, 10, 13, 16. You add 3 each time. Or, if you want a more advanced thing, to work out the nth term in the sequence, the formula is, 3n-2.

Answer: 9

2x+3=21, so 2x=21-3=18 and therefore x=9. If a number is next to a variable (an unknown number, usually shown as x, a, n, etc...) then you have to multiply the variable by that number.

Answer: 13

The rule is that you add the last two numbers to get the next one. This is called the Fibonacci Sequence, after a famous mathematician named Fibonacci.

Answer: 50ml

300ml divided by 6 is 50ml. It doesn't matter what liquid it is, not even if it is Coke, or water! just remember to put your units at the end, like in this question, the units are ml.

Answer: 1/4

9+27=36, so there are 36 apples altogether. The fraction of apples that I have is 1/4, or 9/36. 1/4 is the simplified version, though.

Answer: 730

There are 365 days in a year that isn't a leap year, so doubling it will get you 730. In a leap year, an extra day is added to February, to make the days in February 29, and the days in that year 366. But did you know that a leap year is taken off every four centuries?

Answer: 60 degrees

There are 180 degrees in a triangle, and a triangle has 3 sides. 180 divided by 3 is 60, so therefore, an equilateral triangle has angles of 60 degrees.

Answer: 24

3/4 of 24 is 18. 24-18=6
To find 3/4 of something, you divide the total by 4, and multiply it by 3.
