Answer:(7/8 - 4/5)^2 = 91600 = 0.005625Spelled result in words is nine one-thousand six-hundredths.Step-by-step explanation:Subtract: 78 - 45 = 7 · 58 · 5 - 4 · 85 · 8 = 3540 - 3240 = 35 - 3240 = 340For 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 the both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step the fraction result cannot be further simplified by cancelling.In words - seven eighths minus four fifths = three fortieths
