![]() 1 hectare = 100 meters on each side, so a hectare has 100 m x 100 m = 10,000 m 2.The unit is written in m 3.ġ5) How much is a hectare and how much is square millimetre? Then multiply top and bottom by 10 = 0.7x 10 = 7/10įor each number after the decimal point 1 x 10Ĭubic Meter is the standard unit used to measure the volume of an object length by length.Write down the decimal “over” the number 1 = 0.7/1.To convert a percentage into fraction let say 70% to a fraction Add the “ % “ sign to the answer = 44.44%ġ3) How can you convert a percentage to a fraction?.To convert a fraction to a percentage, we look into an example for 4/9 Sum of exterior angles of the polygon is 360°.ġ2) How can you convert a fraction to a percentage? In polygons, the angle between any side of the shape and a line extended from the next side is referred as Exterior Angles. Solid Geometry: It is about three-dimensional objects like cylinders, cubes, prism, and spheresġ0) What is the difference between Line, Point, Plane and Solid?.Plane Geometry: It is about flat shapes like triangles, lines and circles that can be drawn on a piece of paper.Geometry can be classified into two classes Once you have done with B or O, then proceed from left to right doing any “D” or “M” as it is given in the problem, and then proceed from left to right doing any “A” or “S” as given in the problem. To avoid confusion from where to start the calculation from, you have to follow the BODMAS If one employee earns $1100 and other earns $500, how much will the third employee earn?Ĩ) Explain in a complicated calculation like 8 + (9 x 5 2 +8) from where you will start calculation? Distributive laws say that we can have the same answer while multiplying a number by a group of numbers added together or multiplying them separately and then add them, For example, a x ( b+c) = axb + axcħ) In a small company, the average salary of three employees is $1000 per week.Associative laws say it does not matter how we group the number final value will remain the same, for example, (a+b)+c = (a+b)+c, and same for multiplication.Commutative laws say we can swap numbers, and you still get the same number when you add, for example, a+b = b+a and same for multiplication.The formula for calculating compound interest is PX (1 + r/100) ^tĦ) What is Commutative, Associative and Distributive laws in maths? Where P is the principal amount, R is for the rate of interest and t is for time To calculate simple interest, the formula used is (PX RX T)/ 100 There are two types of interest which can be calculated using a different formula ![]() Remained/ total = 30/ 40 = 3 / 4 is the fraction remain in the rack Mathematics Interview Questionĥ) What is the formula for calculating the interest rate? Now, the second part is 10 of the boxes are in use which means that the total amount of box left is= 40 – 10 = 30. ![]() If each rack consist of 10 boxes of chalk stick, then the total number of the box on 4 racks will be What is the fraction that remains in the rack? In a given day, 10 boxes of chalk stick are in use. of wall space?Ĥ) In a staff room, there are four racks with 10 boxes of chalk-stick.
