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
