Question

The Boardman family walked  two over five   of a mile in   two over seven  of an hour. What is their unit rate in miles per hour

anonymous · Answer

two-sevenths over two-fifths equals     one and two-fifths  miles per hour
  two-sevenths over two-fifths equals         five over seven  mile per hour
  two-fifths over two-sevenths equals     one and two-fifths  miles per hour
  two-fifths over two-sevenths equals         five over seven  mile per hour

HI!!!
$$\frac{2}{5}$$ of a mile in $$\frac{2}{7}$$ of an hour

misty1212 · Answer

is that the question?

anonymous · Answer

yes

misty1212 · Answer

they want you do divide miles by hours 
$$\frac{2}{5}\div\frac{2}{7}$$ you know how to do that?

anonymous · Answer

no, not really. Sorry.

misty1212 · Answer

as the math teachers say "invert and multiply" which means flip the second on and go straight across $$\frac{2}{5}\div \frac{2}{7}=\frac{2}{5}\times\frac{7}{2}$$

misty1212 · Answer

cancel the twos, gives you $$\frac{7}{5}$$

anonymous · Answer

true. But thats not one of my answers.

misty1212 · Answer

maybe they want you to write it as a mixed number, or a decimal

misty1212 · Answer

is $$1\tfrac{2}{5}$$ a choice?

anonymous · Answer

yes

misty1212 · Answer

then pick that one!

anonymous · Answer

So, it would be 2/5 over 2/7 equals 1 and 2/5
