Question

Johnny says that 600 cm is not enough moulding for the baseboards that measure 5642 mm. Is he right in his statement? Explain

Answer 1

Johnny is wrong.

Explanation:

To compare two quantities, they must both be written in the same units. In this case, both must be in centimeters or millimeters. So, we must convert 600cm to millimeters or vice versa.

If we choose to use milimeters, we have

600cm=600cm
`(10mm)/(1cm)`

600cm = (600)(10) mm

600cm = 6000 mm

Now, we must compare 6000 mm with 5642 mm. We can see that 6000mm is greater than 5642 mm. hence, it is enough moulding for the baseboards.

In fact, 6000-5642 mm =358 mm would remain.
