We will convert all numbers to their standard numerical form to compare them.

Step 1 — Comparing 30 thousand and 3 lakhs

First, let us write 30 thousand as a number. We know that 1 thousand is 1,000. So, 30 thousand is 30 times 1,000. $30 \text{ thousand} = 30 \times 1,000$ $= \mathbf{30,000}$

Next, let us write 3 lakhs as a number. We know that 1 lakh is 100,000. So, 3 lakhs is 3 times 100,000. $3 \text{ lakhs} = 3 \times 100,000$ $= \mathbf{300,000}$

Now, we compare 30,000 and 300,000. Clearly, 30,000 is smaller than 300,000.

$\boxed{30 \text{ thousand} < 3 \text{ lakhs}}$

Step 2 — Comparing 500 lakhs and 5 million

First, let us write 500 lakhs as a number. We know that 1 lakh is 100,000. So, 500 lakhs is 500 times 100,000. $500 \text{ lakhs} = 500 \times 100,000$ $= \mathbf{50,000,000}$

Next, let us write 5 million as a number. We know that 1 million is 1,000,000. So, 5 million is 5 times 1,000,000. $5 \text{ million} = 5 \times 1,000,000$ $= \mathbf{5,000,000}$

Now, we compare 50,000,000 and 5,000,000. Clearly, 50,000,000 is larger than 5,000,000.

$\boxed{500 \text{ lakhs} > 5 \text{ million}}$

Step 3 — Comparing 800 thousand and 8 million

First, let us write 800 thousand as a number. We know that 1 thousand is 1,000. So, 800 thousand is 800 times 1,000. $800 \text{ thousand} = 800 \times 1,000$ $= \mathbf{800,000}$

Next, let us write 8 million as a number. We know that 1 million is 1,000,000. So, 8 million is 8 times 1,000,000. $8 \text{ million} = 8 \times 1,000,000$ $= \mathbf{8,000,000}$

Now, we compare 800,000 and 8,000,000. Clearly, 800,000 is smaller than 8,000,000.

$\boxed{800 \text{ thousand} < 8 \text{ million}}$

Step 4 — Comparing 640 crore and 60 billion

First, let us write 640 crore as a number. We know that 1 crore is 10,000,000. So, 640 crore is 640 times 10,000,000. $640 \text{ crore} = 640 \times 10,000,000$ $= \mathbf{6,400,000,000}$

Next, let us write 60 billion as a number. We know that 1 billion is 1,000,000,000. So, 60 billion is 60 times 1,000,000,000. $60 \text{ billion} = 60 \times 1,000,000,000$ $= \mathbf{60,000,000,000}$

Now, we compare 6,400,000,000 and 60,000,000,000. Clearly, 6,400,000,000 is smaller than 60,000,000,000.

$\boxed{640 \text{ crore} < 60 \text{ billion}}$

Answer

(a) 30 thousand < 3 lakhs (b) 500 lakhs > 5 million (c) 800 thousand < 8 million (d) 640 crore < 60 billion
