Q. Noam had a length of 1331cm of ribbon and cut 331 equal-sized strips the full width of the ribbon.How long is each whole strip?cm
Convert to Improper Fractions: Convert the mixed numbers to improper fractions to make the division easier.13(31) cm can be converted to an improper fraction by multiplying the whole number by the denominator and adding the numerator, then placing the result over the original denominator.13(31)=(13×3+1)/3=(39+1)/3=340 cm3(31) can be converted in the same way:3(31)=(3×3+1)/3=(9+1)/3=310
Find Length of Each Strip: Divide the total length of the ribbon by the number of strips to find the length of each strip.The total length of the ribbon is 340 cm, and Noam cut it into 310 equal-sized strips.To find the length of each strip, divide 340 cm by 310.(340)÷(310)=(340)×(103)=1040=4 cm
Check Calculation: Check the calculation for any mathematical errors.We multiplied the reciprocal of 310 to 340, which simplifies to 1040, and that equals 4. There are no mathematical errors in this calculation.
