Answer 2

1) Let's solve the first equation step by step:

Step 1: Simplify the fractions on both sides of the equation. - 3/4 divided by 9/16 is the same as multiplying 3/4 by the reciprocal of 9/16, which is 16/9. So, 3/4 divided by 9/16 is equal to (3/4) * (16/9) = 48/36. - 5/8 multiplied by 4/15 is equal to (5/8) * (4/15) = 20/120.

The equation becomes: 48/36 - 20/120 = ...

Step 2: Find a common denominator for the fractions. - The common denominator for 36 and 120 is 360.

The equation becomes: (48/36) * (10/10) - (20/120) * (3/3) = ...

Step 3: Simplify the fractions further. - (48/36) * (10/10) = 480/360 = 4/3. - (20/120) * (3/3) = 60/360 = 1/6.

The equation becomes: 4/3 - 1/6 = ...

Step 4: Subtract the fractions. - To subtract fractions, we need a common denominator. The common denominator for 3 and 6 is 6.

The equation becomes: (4/3) * (2/2) - (1/6) = ...

Step 5: Simplify the fractions further. - (4/3) * (2/2) = 8/6 = 4/3.

The equation becomes: 4/3 - 1/6 = ...

Step 6: Subtract the fractions. - 4/3 - 1/6 = (4/3) * (2/
