The greatest common factor of 42 and 72 is 6.
6 times 7 is 42. 6 times 12 is 72. There is no greater factor for both numbers except for 6.
Hope this helps!
Remember that ratios are essentially fractions without fraction bars...
If they asked to find the ration of 19.50 to 16.25 you would set them up like so....
19.50 : 16.25 -----> since fractions can be simplified so can ratios in the same manner
the ratio you would end up with is <u>6 : 5</u><u />
Ratios can be easily remembered and solved if you understand the link between them and fractions.
I hope this helps! :D
