Answer:

#31.5#

Explanation:

By definition, #70%# means "seventy parts over a hundred# of something, and again, this means that you must divide your quantity in #100# pieces, and then consider only #70# of those pieces.

This should clarify how we must behave:

  • Divide #45# in a hundred parts: #45/100=0.45#. This is a part every #100# of #45#, namely the #1%# of #45#.

  • We want #70# of these little pieces, so we take #0.45*70=31.5#. This is the #70%# of #45#.
