Noam had a length of [tex]13 \frac{1}{3} \, \text{cm}[/tex] of ribbon and cut [tex]3 \frac{1}{3}[/tex] equal-sized strips from the full width of the ribbon.

How long is each whole strip? [tex]\square \, \text{cm}[/tex]

Answer :

Sure, let's solve this step by step.

Noam had a ribbon of length [tex]\( 13 \frac{1}{3} \)[/tex] cm, which is a mixed number. We can convert this to an improper fraction for easier calculation:
[tex]\[ 13 \frac{1}{3} = 13 + \frac{1}{3} = \frac{39}{3} + \frac{1}{3} = \frac{40}{3} \text{ cm} \][/tex]

Next, Noam cut the ribbon into [tex]\( 3 \frac{1}{3} \)[/tex] equal-sized strips. We also convert this mixed number into an improper fraction:
[tex]\[ 3 \frac{1}{3} = 3 + \frac{1}{3} = \frac{9}{3} + \frac{1}{3} = \frac{10}{3} \text{ strips} \][/tex]

To find the length of each strip, we will divide the total length of the ribbon by the number of strips:
[tex]\[ \text{Length of each strip} = \frac{\frac{40}{3}}{\frac{10}{3}} \][/tex]

When dividing fractions, we multiply by the reciprocal:
[tex]\[ \frac{40}{3} \div \frac{10}{3} = \frac{40}{3} \times \frac{3}{10} \][/tex]

Now, multiply the numerators together and the denominators together:
[tex]\[ \frac{40 \times 3}{3 \times 10} = \frac{120}{30} \][/tex]

Finally, simplify the fraction:
[tex]\[ \frac{120}{30} = 4 \text{ cm} \][/tex]

Thus, the length of each whole strip is [tex]\( 4 \text{ cm} \)[/tex].
