Please exlain how I "use the power of ten to change each to a decimal". I was in a band lesson when my math teacher taught this. Thanks.
4 over 50 9 over 25
4/50= 0.08=8.0*10(exponent-2),exponent-2 means to move the decimal point to the left 2 spaces..
9/25=0.36=3.6*10(exponent-1),the same as the first one, exponent -1 means to move the decimal point to the left 1 space...
to represent exponents in typing, put ^#
your on your own kid
