Question

Naha used 4 green ribbons
and 8 purple ribbons to
make a garland. Each green
ribbon is 30 m long and
each purple ribbon is 20 m
long. What is the difference
in the total lengths of
these ribbons?​

Answer 1

Answer:

40m

Step-by-step explanation:

Length of green ribbon = 30m

Then total length of 4 green ribbons

= 30×4

= 120m

Length of purple ribbon = 20m

Then total length of 8 purple ribbons

= 20×8

= 160m

Difference between their total length

= 160-120

= 40m
