Question

Karen had a roll of ribbon 48 1/2 metres long. How many pieces of ribbon of length 1 1/5 m can she cut from the roll? How many metres of ribbon will be left?

pls solve according to rational numbers

Answer 1

40 ribbons. 5/12 m of ribbon will be left

Explanation:

Divide the total amount of ribbon by the length of each piece of ribbon:

48 1/2 ÷ 1 1/5

Convert the mixed numbers to improper or top heavy-fractions

97/2 ÷ 6/5

Keep - Change - Flip to turn into a multiplication problem

97/2 × 5/6 = 485/12 = 40 5/12

This means she can cut 40 whole ribbons and the remainder is 5/12 meters.
