**(d)** 9830415, 10023001

**Solution:**

**(a)** Here 503 lies on the left of 530 on the number line.

∴ 530 > 503

**(b)** Here 307 lies on the left of 370 on the number line.

∴ 370 > 307

**(c)** Here 56789.lies on the left of 98765 on the number line.

∴ 98765 > 56789

**(d)** Here 9830415 lies on the left of 10023001

∴ 9830415 > 10023001
