# Which is greater?

(a) 0.3 or 0.4

(b) 0.07 or 0.02

(c) 3 or 0.8

(d) 0.5 or 0.05

(e) 1.23 or 1.2

(f) 0.099 or 0.19

(g) 1.5 or 1.50

(h) 1.431 or 1.490

(i) 3.3 or 3.300

(j) 5.64 or 5.603

**Solution:**

We will be using the concepts of inequalities to solve this.

(a) 0.3 or 0.4

We know that, 0.3 = 3/10, 0.4 = 4/10 and 3/10 < 4/10.

Thus, 0.4 is greater than 0.3

(b) 0.07 or 0.02

As we know, 0.07 = 7/100, 0.02 = 2/100 and 7/100 > 2/100

Thus, 0.07 is greater than 0.02.

(c) 3 or 0.8

3 is greater than 1 and 0.8 is lesser than 1.

Hence, 3 is greater than 0.8.

(d) 0.5 or 0.05

0.5 can also be written as 0.50.

Hence, 0.50 = 50/100, 0.05 = 5/100.and 50/100 > 5/100,

Hence, 0.5 > 0.05

(e) 1.23 or 1.2

As 1.23 = 123/100, 1.2 = 12/10 = 120/100 and 123/100 > 120/100

Hence, 1.23 > 1.2

(f) 0.099 or 0.19

As 0.099 = 99/1000, 0.19 = 190/1000 and 190/1000>99/1000

Thus, 0.19 > 0.099.

(g) 1.5 or 1.50

As 1.5 = 15/10 = 150/100, 1.50 = 150/100.

The values obtained are equal, so 1.5 = 1.50.

(h) 1.431 or 1.490

We know that, 1.431 = 1431/1000, 1.490 = 1490/1000 and 1431/1000 < 1490/1000

Thus, 1.490 > 1.431.

(i) 3.3 or 3.300

3.3 can be expressed as 3.3 = 3.300 = 3300/1000, 3.300 = 3300/1000

Since their values are equal, 3.3 = 3.300.

(j) 5.64 or 5.603

5.64 = 5.640 = 5640/1000, 5.603 = 5603/1000 and 5640/1000 > 5603/1000

Hence, 5.64 is greater than 5.603.
