First the thing you need to know before answering the question is, the probably of not getting something is [ 1 - the probabilty of getting something ], so the probabilty of getting a blue sweet is , the ...

so first you add the two ratio, so 4+6 = 10. So now we know that we have 10 parts that we can give out. One part is equal to 50/10 = 5, one part has 5 sweets. so bob gets 4 parts, 4 x 5 = 20 and bill gets...

If u can recall the formula for Pythagoras’ in a right angle triangle. Its a^2 + b^2 = c^2 , where C is the hypotenuse. As you can tell from the question , we have been given 2 sides. Now you will need to...

As you can see from the question there are 6 parts that 270 needs to be divided by. One sixth of 270 is equal to 45 and so one of the parts is equal to 45. To get the ratio, you have to simply multiply th...

Firstly, lets name each equation A and B- this will help us later. If I told you what x was, you would be able to use either equation to find y- easy! so lets first find one unknown (x or y) then use that...
