If using just one string, only some of the strings of beads can be used to make 1/2. Which ones? Why? | If using just one string, only some of the strings of beads can be used to make 1/2. Which ones? Why? | ||
To show that the solutions which use more than one string are correct, use the Lowest Common Denominator (LCM) method, for example for the case of 1/3 +1/6 = 1/2 | |||
1/3 + 1/6 = | |||
2/6 + 1/6 = | |||
(2+1)/6 = | |||
3/6 = | |||
1/2 | |||
How do you know if you have found all the solutions? | How do you know if you have found all the solutions? | ||
