On monday morning, there was 1/12 inch of rain. on monday afternoon, there was 1/6 inch of rain. how much rain fell on monday?

3/12 inches of rain fell on monday, because 1/6 is the same as 2/12.

2/12+1/12=3/12

Hope this helps!

You need to covert 1/6 into the same denominator as 1/12

That means 2/12 is equal to 1/6 and can combine with 1/12

2/12 + 1/12 makes 3/12

You simplify to make it 1/4 because it can divide by 3
