A length of string is 42 1/2 inches long.

A teacher needs to make 8 equal

length pieces from the string. How

long should she make each piece?

A - 5 5/16 inches

B - 8 1/2 inches

C - 21 1/4 inches

D - 34 1/2 inches

Answer: 5 5/16 inches

Step-by-step explanation:

3 ways to get this.

1. Estimate. You know that 8 * 5 is 40, and 40 is close to 42. 40 : 8 is 5

There is only one answer close to that so choose A.

2. Calculate. Change the numbers to a decimal and divide: 42.5 : 8 = 5.3125

3. Fraction multiplication and division: Make 42 1/2 into an "improper fraction"

and multiply. 85/2 * 1/8 = 85/16 Divide "old style" long division to get a remainder. 85 : 16 = 5, remainder 5. Put the remainder 5 over the divisor 16 to end up with 5 5/16

5 5/16

Step-by-step explanation:

you just divide 42 1/2 by 8
