Here is one way to calculate 239 + 9: Ten nines make 90. Another 10 nines make 180. Five more nines make 225. One more nine makes 234. Another five ones make 239. All together that's 26 nines, with 5 left over. So, the answer is 26, remainder 5. Write a string of equations that incorporates this reasoning. Make sure that your equations include the above reasoning with the distributive property to get the answer to 239 +9. Start your equations with: 239 5. Calculate 100 +7 without using a calculator or a long division procedure. Use reasoning such as multiplication, addition and or subtraction. (similar to question 4) 6. When two fractions have common denominators, we can divide them just be dividing their numerators. Show why+-? is equivalent to solving 9-3=?. Use a strip diagram to explain this
