Treat both numbers as whole numbers - i.e 76 x 325 (remember at the end that there are still decimals!) 76 x 325 = 24,700 ( This will be explained by using the two lines by 1st method or method that the s...

We need to multiply x by powers of 10 in order to get the recurring part on its own after the decimal point, and then be able to eliminate it. 10x = 4.363636... and 1000x = 436.363636...So subtracting we ...

Change the inequality to an equalsx² -2=2solve as normalx² -2=2-2x² -4=0factorise(x-2)(x+2)=0so x=-2 and x=2However, how do you know if the answer is bigger or smaller tha...

The equation for the volume of a cylinder is (1/2)pi(r²)*H, where r is the radius and H is the height of the cylinder. For the cylinder given, the volume is therefore (1/2)pi(...
