Thank you very much········ 1. In rectangles of the same size, use shadows to represent one third, two sixths and nine thirds. Can you find any relationship between them 2. Use 1,2,3,4 to form four fractions. The molecules of the four fractions are the same and the denominators are different. Compare their sizes 3. Fill in the appropriate score in brackets 24 min = () H 70 cm = () m 327 g = () kg 163 square decimeters = () square meters 15 minutes = () hours 235 kg = () tons 4. If the fractional unit is one in fifteen, the maximum true fraction is (), plus () such fractional units is the minimum prime number; if the minimum false fraction is (), plus () is the minimum composite number 5. The denominator of a fraction is four times more than the numerator. 3. The sum of numerator and denominator is 23. What is the fraction?

They are all the same shadow
2.1\2>1\3>1\4
3.2\5 7\10 327\1000 163\100 1\4 47\200
4.15\15 29 1\15 59
5. If the numerator is x, the denominator is 4x + 3
x+4x+3=23
x=4
So the score is 4-19
