Question

Jessica is measuring three lengths of
ribbon. The first one is 30 cm, the second one is 45 cm, and the last one is 18 cm. How long are all 3 ribbons in cm? How long are all 3 in mm? If she wants to add one more ribbon to make exactly one meter (100cm), how long will that 4th ribbon need to be in cm and mm?
2. Susan begins a new walking program with 200 m on the first day. Each day, she will increase her walk by 200 m. How many kilometers will she walk on day 15 of her program? Remember – 1000m equals 1 km. How many days will it take her to walk a total of 5km?

Answer 1

Add them up and you'll get the ribbons length in cm.
Than take 48 and convert them into mm
