Solve the problems 5/3*-6/2
Correct Answer
-30/6
-5Explanation
The given expression involves the division and multiplication of fractions. To solve it, we first multiply 5/3 by -6/2, which gives us -30/6. This fraction can be simplified to -5 when we divide both the numerator and denominator by 6. Therefore, the correct answer is -30/6, -5.Rate this question:

-5/2 / -4/6=
Correct Answer
20/12
5/3Explanation
The given expression is a division of two fractions. To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. In this case, the reciprocal of -4/6 is -6/4 or -3/2. Therefore, -5/2 divided by -4/6 is equal to -5/2 multiplied by -3/2, which simplifies to 15/4 or 3 3/4. However, none of the given answer options match this result. Therefore, the correct answer is not available.Rate this question:

-6/11 * 5/8 =
Correct Answer
-30/88
-15/44Explanation
The given expression is a multiplication of two fractions. To multiply fractions, we multiply the numerators and denominators separately. In this case, multiplying -6/11 and 5/8 gives us (-6 * 5) / (11 * 8) = -30/88. Therefore, the correct answer is -30/88.Rate this question:
