The best thing to do is to find out what 1/7 is.
9/7= 1.28
1.28x3= 3.84
Therefore 3/7 of 9 is 3.84
Hope this helps :)

In math, "of" almost always means "times".

So your question is: 3/7 times (the number) = 9

Multiply each side of that equation by 7 : 3 times (the number) = 63

Divide each side by 3 : <em> The number = 21</em>

Tom has a piece of rope that is 105 feet long. He wants to cut the rope into 5 equal pieces. How long will each piece be?

goblinko [34]

Hey there!

$\large\boxed{21 ft}$

If he is going to cut it into 5 equal pieces then we need to divide 105 by 5.

105 ÷ 5 = 21

So, each piece will be 21 feet long.

Hope this helps!
