Question

Jenny sells lottery tickets worth 1880 and gets a commission of 376 . if Sonia got a commission of 648 . how much worth of tickets she sell

Answer 1

she takes 376 from 1880 tickets
she takes 1 from 1880/376 = tickets
similarly,
she takes 648 from 648x5 = 3240 tickets.

Answer 2

1880:376=x:648

If 376×5=1880

So 648×5=3240

So x=3240
