Question

How do you convert 75 mm to centimetres?

Answer 1

Hint: We first find the relation between millimetre and centimetre. The measurement is common in measurement units. We find the relation as 1 mm being equal to $0.1$ cm. We use the unitary system, to find the length of the 75 mm in cm.

Complete step-by-step answer:
We need to convert the length by changing its unit from millimetre to centimetre.
We find the relation between millimetre and centimetre 1 mm being equal to $0.1$ cm.
We already have that in the unitary system. The unitary method is a method in which we find the value of a unit and then the value of a required number of units. The unitary method is also used to find the value of a single unit from a given multiple.
We need the equivalent length of 75 mm.
We multiply 75 with $0.1$ to get the length which will be equal to 75 mm.
Therefore, 75 mm is equal to $75\times 0.1=\text{7}\text{.5}$ cm.
Therefore, 75 millimetre is equivalent to $\text{7}\text{.5}$ centimetre.

Note: The millimetre and centimetre are units of measurement for length in both the US customary units and the metric systems of measurement. This unit is used in the normal or common measurement units. It can also be changed to other common measurement units using the relation in the metric system.
