Answer is 3. How many 1/4 m pieces of ribbon are needed to have a total of 3 1/2 m of ribbon
Step-by-step explanation
3 1/2 m ribbon divided by 1/4
When you divide a fraction, flip the divisor and multiply
3 1/2 x 4/1
7/2 x 4/1
28/2 = 14 pieces of 1/4m long ribbon will equal to 3 1/2 m total
Check your work
14 x 1/4 = 14/4, simplify to 3 1/2 m.
Solution is correct
