Step-by-step explanation:
Subtract: -35 - (-57) = -3 · 75 · 7 - (-5) · 57 · 5 = -2135 - (-2535) = -21 - (-25)35 = 435
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 the both denominators - LCM(5, 7) = 35. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 7 = 35. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - minus three fifths minus minus five sevenths = four thirty-fifths
