Question

4) Compare 0.0008695 and 0.000538.Solve by writing them in standard form.
5) In a stack ,there are 9 books ,each of thickness 0.0015 m and 12 thick sheets, each of thickness
0.000015 m. Find the total thickness of the stack.

Answer 1

Answer:

answer the first question-

standard form of 0.0008 695 = 8.695 * 10 raise to the power -4

standard form of 0.0005 38 is =5.38 8 * 10 raise to the power -4

now compare both of them

8.695 * 10 raise to the power -4 > 5.38*10 raise to the power -4

answer of the second question

we can convert the unit metre to centimetre to make our calculation easier-

so 0.0015 metre with be equal to 0.15 cm

and 0.000015 metres will be equal to 0.0015 centimetres

nine books of 0.15 cm means total thickness of 1.35 centimetres

and 12 sheets of thickness 0.0015 CM means total thickness of 0.0 180 cm

so the total thickness will be 0.0180 + 1.35

= 1.3680cm

Answer 2

Answer:

Step-by-standard form of 0.0008 695 = 8.695 * 10 raise to the power -4

standard form of 0.0005 38 is =5.38 8 * 10 raise to the power -4

now compare both of them

8.695 * 10 raise to the power -4 > 5.38*10 raise to the power -4

answer of the second question

we can convert the unit metre to centimetre to make our calculation easier-

so 0.0015 metre with be equal to 0.15 cm

and 0.000015 metres will be equal to 0.0015 centimetres

nine books of 0.15 cm means total thickness of 1.35 centimetres

and 12 sheets of thickness 0.0015 CM means total thickness of 0.0 180 cm

so the total thickness will be 0.0180 + 1.35

= 1.3680cm
