1. 0.06=?

a)3/5 b)(3/50) c)(3/500) d)none of these

Solution:-

a. (3/50)

Because,

=0.06

= (6/100) … [÷ 2]

= (3/50)

2. 1.04 =?

a) [1(1/50)] b)[1(2/5)] c)[1(1/25)] d)none of these

Solution:-

C) [1(1/25)]

Because,

=1.04

= (104/100)

= (26/25) … [÷ 4]

= [1(1/25)]

3. [2(2/25)] = ?

a)2.8 b)2.08 c)2.008 d)none of these

Solution:-

b) 2.08

Because,

= [2(2/25)]

= (52/25) … [÷ 25]

= 2.08

4. 6cm =?

a)0.006km b)0.0006km c)0.00006km d)none of these

Solution:-

C) 0.00006km

WKT,

=1m = 100 cm

Then,

= 6cm

= (6/100) m

= 0.06m

WKT,

= 1km = 1000m

Then,

= 0.06m

= (0.06/1000)

= (0.00006) km

5. 70 g =?

a)0.7kg b)0.07kg c)0.007kg d)none of these

Solution:-

B) 0.07kg

WKT,

= 1 kg = 1000g

= 70 g

= (70/1000)

= 0.07 kg

6. 5kg 6g =?

a)5.0006kg b) 5.06kg c)5.006kg d) 5.6kg

Solution:-

C) 5.006kg

WKT,

= 1 kg = 1000g

= 5kg = 5000g

= 5000 + 6

= 5006g

= (5006/1000)

= 5.006kg

7. 2 km 5 m =?

a)2.5km b)2.05km c)2.005km d)2.0005km

Solution:-

c) 2.005km

WKT,

= 1 km = 1000m

= 2 km = 2000m

= 2000 + 5

= 2005m

= (2005/1000)

8. (1.007-0.7) =?

a)1 b)0.37 c)0.307 d)none of these

Solution:-

C) 0.307

First convert the given decimals into like decimals

= (1.007 – 0.700)

= 0.307

9. What should be subtracted from 0.1 to get 0.03?

a)0.7 b) 0.07 c)0.007 d)none of these

Solution:-

C) 0.07

Let us assume the missing number be x,

Then,

= 0.1 – x = 0.03

By sending – x from left hand side to the right hand side it become x and 0.03 from right hand side to the left hand side it become -0.03. We get,

= 0.1 – 0.03 = x

= 0.07

10. What should be added to 3.07 to get 3.5?

0.57 b)0.34 c)0.43 d)0.02

Solution:-

C) 0.43

Let us assume the missing number be x,

Then,

= 3.07 + x = 3.5

By sending 3.07 from left hand side to the right hand side it become -3.07. We get,

= 3.5 – 3.07 = x

= 0.43
