Final answer:
To solve the equation 7/8 + 12 = 30, subtract 12 from both sides and then multiply both sides by 8.
Step-by-step explanation:
To solve this equation, first subtract 12 from both sides to isolate the fraction: 7/8 = 30 - 12. This simplifies to 7/8 = 18. Next, to solve for the fraction, multiply both sides by 8 to get rid of the denominator. This gives us 7 = 18 * 8. Finally, multiply 18 by 8 to find the value of the fraction: 7 = 144.
