need to add the two together. To do so we add 60 and 2/3 to 5 and 1/2. But to add the fraction component we need the bottom of both to match, finding the lowest common denominator. Also to multiply the top by any multiple of change at the bottom.
Now the equation is 60 and 4/6 + 5 and 3/6 litres. WE can add them, 60+5 and 4/6 + 3/6 equal to 65 and 7/6 litres. The 7/6th component is also the same as 6/6 + 1/6. the 6/6 is a whole so we have 66 litres and 1/6 total. The 1/6 is 1000/ 6 to find out the value in millilitres. I'l leave that to you.
here is a calculator. Just plug the numbers and same sign in as you would a normal calculator for a straight forward answer..
the lowest common denominator, is the lowest number which is a multiple of both fractions bottoms. When we multiply the bottom on either or both we need to make the top also multiplied by the same amount. Means 3/4 and 4/3 we need 12 on the bootom of both, the 3/4 is multiplied by 3 on the bottom and the 4/3 multiplied by 4 on the bottom so we multiply the top of both respectively as given.
