Question

Bella ordered Christmas presents online through Amazon Prime. She noticed 2 out

of every 5 orders was wrong. If she ordered 45 presents through Amazon, how
many can she expect to be wrong?

Answer 1

so i do math a weird way but i’ll try to explain it and i’ll have the answer at the bottom

so 2/5 is 40%

40% of her orders are wrong

40% of 45 = 45•0.4

this equals 18

she should expect to receive 18 amazon packages that are wrong

Answer 2

18
