Question

A piece of wood that is 3/4 meter long is being cut into smaller pieces that are each 1/10 meter long. Which equation could be solved as the first step to find the number of pieces, n that can be made?

a) n=3/4x1/10
b) n=3/4 x10/1
c) n=10/1x4/3
d) n=1/10x3/4

Answer 1

Divide the whole piece (3/4 meters) by the portion size of 1/10 meter.

=3/4 ÷ 1/10
to divide fractions, we multiply by the reciprocal/inverse of 1/10
=3/4 * 10/1

ANSWER: B) n= 3/4 * 10/1

Hope this helps! :)
