Question 2
1 / -0

Solve the given
$$3.005+4.7$$

A
$$3.052$$

B
$$3.475$$

C
$$7.705$$

D
$$3.007$$

Solution

Addition of $$3.005$$ and $$4.7$$ gives $$3.005+4.7=7.705$$
Question 3
1 / -0

The value of 30.5 - 30.4 + 30.3 - 30.2 + 30.1 - 30 + 29.9 - 29.8 + 29.7 - 29.6 + 29.5 - 29.4 + 29.3 - 29.2 + 29.1 - 29.0 = _________.

A
$$0.8$$

B
$$0.7$$

C
$$0.6$$

D
$$1.8$$

Solution

We have, $$(30.5 - 30.4) + (30.3 - 30.2) + (30.1 - 30) + (29.9 - 29.8) + (29.7 - 29.6) + (29.5 - 29.4)
+ (29.3 - 29.2) + (29.1 - 29.0)$$

$$= 0.1+ 0.1 + 0.1 + 0.1 + 0.1+ 0.1 + 0.1 + 0.1$$

$$= 0.8$$.
Question 4
1 / -0

Shalini's car has $$15\ L\ 315\ ml$$ of petrol in its tank, while her scooter has $$2\ L\ 945\ ml$$ of petrol in its tank. How much petrol is there in both the vehicles altogether?

A
$$18\ L\ 370\ ml$$

B
$$18\ L\ 260\ ml$$

C
$$13\ L\ 945\ ml$$

D
$$13\ L\ 370\ ml$$

Solution

Quantity of petrol in car $$= 15\ L\ 315\ ml$$
Quantity of petrol in scooter $$= 2\ L\ 945\ ml$$
$$\therefore$$ Total quantity of petrol
$$= (15\ L+315\ ml) +( 2\ L+ 945\ ml)$$
$$=17\ L+1260\ ml$$
$$=17\ L+ (1\ L +260\ ml)$$
$$= 18\ L\ 260\ ml$$.
Question 5
1 / -0

What is the missing number in the box?
$$600.0651 = 600 +$$ _____ $$+ 0.005+ 0.0001$$

A
$$0.005$$

B
$$0.06$$

C
$$0.5$$

D
$$5$$

Solution

$$600.0651 = 600+ \dfrac{6}{100} +\dfrac{5}{1000} +\dfrac{1}{10000} = 600 + 0.06 + 0.005 + 0.0001$$.
Question 6
1 / -0

Subtract the given decimals: $$4.17$$ from $$5.5$$

A
$$1.33$$

A
$$0$$ and $$1$$

B
$$1$$ and $$2$$

C
$$2$$ and $$3$$

D
$$-1$$ and $$0$$

Solution

A positive decimal always lies between the number on left side of the decimal and its successor .
In $$1.9$$ the number on the left side of decimal is $$1$$ .So the decimal number lies between $$1$$ and $$2$$.
Question 8
1 / -0

Find the value of $$617+6.017+0.617+6.0017$$.

A
$$6.2963$$
