Step-by-step explanation:
My mom has trouble understanding math... I decided to give her an easy equation. 3/6 km+1/5km = 15/40 +8/40. She asked me what I did. I told her that I multiplied both equations to get a denominator of 40. Then she said "what about those top ones" "oh... well" I said " whatever I multiplied to the bottom I have to do to the top!" Anyway back to the problem. Well... somehow all of this equals 23/40. This is because when you add 15 + 8 that equals 23! So wait a sec what is this on the bottom she asked. well... I am unsure why don't you tell me. She said that the 4 needed to have been added to it.. but the four was too much so they took away one. Good enough! The answer is 3 and 17/40

1) count and mark so that you will have 50 blocks to work with. Shade 19 of those blocks. This will represent your fraction. To get the % divide 19/50= 0.38 move the decimal to the right two places and you will have 38%.
2) do the same count and mark off 20 blocks and shade 13. This represents the fraction. Divide 13/20 = 0.65. Move the decimal two places to the right and you will have 65%.
Answer:
Step-by-step explanation:
Set up a proportion with corresponding sides. The two sides marked with a small line in them represent that those sides are equal. Therefore, the side marked 30 is broken into two lines of equal length (each 15).
Thus, we can set up the following proportion:
