Multiplication first: 2.5 * 2 = 5.0. Then addition: 1.5 + 5.0 = 6.5.
First add the like fractions: 3/8 + 5/8 = 8/8 = 1. Then subtract: 1 - 1/2 = 1/2.
Calculate 'of' parts: 2/5 * 50 = 20. 1/4 * 20 = 5. Subtraction: 20 - 5 = 15.
Solve bracket: 1/2 + 1/3 = 3/6 + 2/6 = 5/6. Multiply by 6: (5/6) * 6 = 5.
LCM of 8, 2, and 4 is 8. Rewrite: 7/8 - 4/8 + 2/8. Combine numerators: (7 - 4 + 2) / 8 = 5/8.
Follow BODMAS. Division first: (3/4) * (2/1) = 6/4 = 3/2. Then multiplication: (1/3) * (3/2) = 1/2.
'Of' means multiplication. 4/5 * 25 = 20. Then add 10 to get 20 + 10 = 30.
Convert to improper fractions: 5/2 + 13/4. Make denominators equal: 10/4 + 13/4 = 23/4. Convert back to mixed: 5 3/4.
Change division to multiplication by flipping the second fraction: (5/6) * (18/15). This simplifies to (5/15) * (18/6) = (1/3) * 3 = 1.
Multiply numerators and denominators: (3 * 8) / (4 * 9) = 24 / 36. Simplify by dividing by 12 to get 2/3.
