He can make 18 pieces. Observe:
22.5/1.25=18
Just use a calculator.
You can simply multiply all the combinations of 3,5, and 7 in pairs:
1) 3 * 5 = 15
2) 3 * 7 = 21
3) 5 * 7 = 35
Don't forget the numbers multiplied to itself:
4) 3 * 3 = 9
5) 5 * 5 = 25
6) 7 * 7 = 49
There are 1760 yards in one mile and the rink is 250 yard in perimeter.
This means 3 miles is 5280 yards.
If Sam has already gone around the whole rink 6 times, that means he was traveled a total of 1500 yards.
Sam has 3780 more yards to travel 3 miles.
This means he needs to do 15.12 more laps around the rink. Or 16 if you are rounding.
Hope this helps! :)
The ratio can not go exactly in 10:9
