how many eighths are there in 72 1/4

Sagot :

Option 1 Solution:
1) Change 72 1/4 to improper fraction, then divide by 1/8
   
 289/4 ÷ 1/8 = N
 289/4 × 8/1 = N (when dividing by a fraction, change the divisor to its reciprocal,
                             then proceed to multiplication)
  N = 578.  There are 578 eighths (578/8) in 72 1/4.

Option 2 solution:
1) Change the dividend and divisor to decimal form.
    72 1/4 = 72.25
      1/8 = 0.125
  
   Divide:
    72.25 ÷ 0.125 = 578.  There are 578 eighths (578/8) in 72 1/4.
