Answer 2

1) 147/64=2 19/64
2) 3-2 19/64=45/64
3) 45/64 : 4 1/16= 9/52+3/4=12/13

Answer 3

Sure, let's solve the expression step by step:

Step 1: Simplify the fraction (3 - 1 47/64) and convert it to an improper fraction. 3 - 1 = 2 1 47/64 = (64 + 47) / 64 = 111/64

So, the expression becomes: 2 111/64

Step 2: Convert the mixed number (2 1/4) to an improper fraction. 2 1/4 = (2 * 4 + 1) / 4 = 9/4

Step 3: Raise the fraction (9/4) to the power of 2 (square it). (9/4)^2 = (9/4) * (9/4) = 81/16

Step 4: Add the result of step 3 (81/16) to 3/4. 81/16 + 3/4 = (81 + 12) / 16 = 93/16

Step 5: Finally, divide the result of step 1 (2 111/64) by the result of step 4 (93/16). (2 111/64) / (93/16) = (127/64) / (93/16)

Now, to divide fractions, we multiply the first fraction by the reciprocal of the second fraction:

(127/64) * (16/93)

Step 6: Multiply the numerators and denominators: (127 * 16) / (64 * 93) = 2032 / 5952

Step 7: Simplify the fraction (if possible): The fraction 2032/5952 can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 16: 2032 ÷ 16 = 127 5952 ÷ 16 = 372

So, the simplified fraction is 127/372.

Therefore, the final result of the expression is 127/372.
