collins bottle of water is 5/6 full. After school the bottle is 1/3 full. Write the difference of the amounts before school and after school

Answer: 1/2 of the bottle

Step-by-step explanation: Hi there,

To do this, we need to have a common denominator (The lower number). To do this, we can multiply the numerator (top) and denominator (bottomem) by 2 and it will not change the value. We can do this because we are multiplying by 2/2, which is the same as 1. By doing this, you end up with 2/6 (because 1/3 * 2/2 = 2/6) and now we can subtract. To subtract 5/6 and 2/6, you can subtract the numerators (top) and leave the denominator the same. 5/6 - 2/6 = 3/6, or 1/2, thus he drank 1/2 of the bottle.
