5.2
÷
0.4
=
13
Step-by-step explanation:
We need to see how many lots of
0.4
will fit into
5.2
. This is represented by:
5.2
÷
0.4
which may also be written as
5.2
0.4
Ok! If it is the decimal that is giving you problems do this:
Multiply by 1 and you do not change the value. However, 1 comes in many forms.
