Question

one insect is 47 millimeters long.another insect is 3 centimeters long. what is the length in millimeters of the insects.

Answer 1

the prefix centi means hundredths; the prefix milli means thousandths.

there are 10 millimeters in one centimeter;

the insect having length 47 mm is 4.7 cm long;

an insect 3 cm long is 30 mm in length.

Answer 2

I am guessing that you are asking for the total length of both insects.

This is obtained by adding the two together.

total length = length(insect 1) +length(insect 2) 

total length = 47 mm +3 cm(10mm/cm)                 add, converting cm to mm

total length = 47 mm +30 mm

total length = 77 mm
