For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(1,4)=4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 4 = 4. In the next intermediate step, , cancel by a common
factor of 4 gives 43/1 .
In words - forty-five minus eight quarters = forty-three.

Answer:
43
Step-by-step explanation:
1.Exponentiation: 3 ^ 2 = 9
2.Subtract: 9 - 4 = 5
3.Multiple: the result of step no. 1 * the result of step no. 2 = 9 * 5 = 45
4.Subtract: the result of step no. 3 - 8/4 = 45
- 8/4 = 45/1 - 8/4= 45 · 4/1 · 4 - 8/4 = 180/4 - 8/4 = 180 - 8/4 = 172/4 = 4 · 43/4 · 1 = 43
