Fraction is smaller than integer. (×)
The numerator of a false fraction is greater than the denominator. (× )
If B is twice that of A (a≠0), then the greatest common factor of A and B is A, and the smallest common multiple is b(√).
The common factor of numerator and denominator is only 1, and fraction is the simplest fraction. (√ )
Have you ever heard the expression "the tip of the iceberg"? Only a small part of the iceberg is exposed to the water, and most of it is hidden under the water. Suppose the volume of the iceberg is 1000 m3, and its exposed volume is1000 m3. The volume of icebergs exposed to the water accounts for (1)/(kloc-0/0) of the total volume, and the volume below the water accounts for (9)/( 10) of the total volume.
25cm = 1/4m 36dm 2 = 9/25 m2 600g = 3/5kg 750ml = 3/4L 0.28dm = 7/25dm
258cm3 =129/500mm3 The number of fifth-grade students wearing glasses is 45/ 150=3/ 10.
5 1 class wears glasses, accounting for 2/9 of the whole class10/45.
3/ 10=27/90
2/9=20/90
2/9 < 65438+3/00
A: The fifth grade 1 Ban Dai is less nearsighted than the fifth grade.
5: Find the greatest common factor of 48 and 54, and their greatest common factor can be obtained by enumeration or short division, so the maximum number of people in each group is 6.
6: The first 0.9 yuan, the second 2÷3≈0.67 yuan, and the third 4÷5=0.8 yuan.
0.67 one fifth > four fifths > (three fourths) > seven tenths
The least common multiple of 8. 4 plus 6 is 12 yuan. 12+2= 14 (yuan)
A: Aunt Li brought at least 14 yuan.
