Marisa finished painting 3/5 of a wood fence before her morning break and 3/10 of the fence between her morning break and her lunch break. Explain how Marisa can find the total amount of fence she painted.
I would want to multiply 3/5 by 2 to get both equations compatible. Then add them together. 3/5 times 2 is 6/10. Then add 6 + 3 = 9. The fence is 9/10 painted.
See the following: 3/5 + 3/10 Put 3/5 + 3/10 over the common denominator 10. 3/5 + 3/10 = (2×3)/10 + 3/10: (2×3)/10 + 3/10 2×3 = 6: 6/10 + 3/10 6/10 + 3/10 = (6 + 3)/10: (6 + 3)/10 6 + 3 = 9: Answer: 9/10
