Zorluk: KolayFraction Multiplication and Division in Context

Read the scenario and determine the total number of pieces that can be cut. Enter your numerical answer in the blank.

Cevap:A quartermaster has a 5050-yard spool of parachute cord. They need to cut the entire spool into smaller pieces that are each 1231 \frac{2}{3} yards long. They will be able to cut a total of 【30】 pieces.

Cevap

30
To find how many smaller pieces can be cut from a larger total, you must divide the total length (5050 yards) by the length of each individual piece (1231 \frac{2}{3} yards). First, convert 1231 \frac{2}{3} to the improper fraction 53\frac{5}{3}. The problem then becomes 50÷5350 \div \frac{5}{3}. To divide by a fraction, multiply by its reciprocal: 50×3550 \times \frac{3}{5}. Multiply 5050 by 33 to get 150150, then divide by 55 to get 3030 pieces.

Adım Adım Çözüm

1
Identify the total length of the cord and the length of each individual piece.
The total length is 5050 yards, and the length of each piece is 1231 \frac{2}{3} yards.
These values are required to set up the division expression.
2
Convert the mixed number to an improper fraction.
123=1×3+23=531 \frac{2}{3} = \frac{1 \times 3 + 2}{3} = \frac{5}{3}
Fraction division is performed using improper fractions rather than mixed numbers.
3
Set up the division problem by dividing the total length by the length of one piece.
50÷5350 \div \frac{5}{3}
Dividing the total quantity by the size of each individual part gives the total number of parts.
4
Multiply the total length by the reciprocal of the fraction.
50×35=1505=3050 \times \frac{3}{5} = \frac{150}{5} = 30
To divide by a fraction, you multiply by its reciprocal.
