HELP! fraction~
Without actually multiplying, can you tell which of the following two is greater? Explain your reasoning.
26 5/7 × 9 or 26 × 9 5/7

Re: HELP! fraction~
Hi LALALA;
Expand them out.
Subtract 9(26) from both sides.
Now can you see that 26 ( 5 / 7 ) is greater than 9 ( 5 / 7 )? So the second fraction is bigger.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
