Answer 1

Answer:

LCM of 2, 4, 10, 5,

LCM = 2 × 2 × 5 = 20

1 × 10 = 10

2 × 10 20

3 × 5 = 15

4 × 5 20

7 × 2 = 14

10 × 2 20

4 × 4 = 16

5 × 4 20

Ascending Order

10 < 14 < 15 < 16

20 20 20 20

Answer 2

Answer:

L.C.M of 2,4,10,5 = 20

$\frac{1 \times 10}{2 \times 10} = \frac{10}{20} \\ \frac{3 \times 5}{4 \times 5} = \frac{15}{20} \\ \frac{7 \times 2}{10 \times 2} = \frac{14}{20}$

$\frac{4 \times 4}{5 \times 4} = \frac{16}{20}$

now arrange in ascending order - 10 < 14 < 15 < 16

so, 1/2 < 7/10 < 3/5 < 4/5.

descending order --------

4/5 > 3/5 > 7/10 > 1/2
