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

(fractions)

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

ok
