Some bikes ad trikes are on a playground. There are 7 seats and 19 wheels. How many bikes? How may trikes are there? Show work.

Answer 1

1 bike = 2 wheels, one seat
so 19 /2 =9.5 =9 wheels
4 bikes
one tricycle = 3 wheels one seat
6 trikes

Answer 2

Danielle, your answer can't be right, since
4 bikes and 6 trikes would make 10 seats, not 7 as needed

Since this is labeled grade 1, we can't use algebra, so ...
let's make a chart

bike - trike - number of wheels

1 ...... 6 .......... 20
2 ...... 5 .......... 19
ahhh, got it

so 2 bikes and 5 trikes
