Question

Decide whether each proposed multiplication or division of measurements is possible. If it is possible, write the result in the last column of the table. proposed multiplication or division Is this possible? result 2 yes 250 mm 0.050 m x 6 ? (9.0 mL). (4.0 mL) = ? 15.8, = ? 5.0 cm

Answer 1

The only thing that needs to be kept in mind while adding, subtracting and multiplication, is the similarity of units. Division can take place when the units lead to some quantity like in the 3rd part of this question, it leads to units of density. Similar units cancel and can be added, subtracted or multiplied. The second part's result is 36 (mL)² which is equivalent to 36 Micro (Litre)² and 36 x 10^-6 L².

_Proposed Mulli plication or Division, Is it Possible? Result YES 5mm 250 mm² 0.050 m Solution : 1 mm = 10-3 m 1 mm² = 10-6 m² So, = 5000 x 10-6 m 250 x 10-6 m² 0.050 m = 5 x 10-3 m = 5 mm 12. (9.0 mL). (4.0ML) YES 36.0 mL? Solution : 9x4 = 36 ML XML = mL? (9.0mL).(4.0 mL) = 36.0 mL?
