Answer 2

To solve the equation -5/7a = 1 17/28, we need to isolate the variable "a" on one side of the equation. Let's proceed with the steps:

Step 1: Convert the mixed number (1 17/28) to an improper fraction. 1 17/28 = (28 * 1 + 17) / 28 = 45/28

Step 2: Rewrite the equation with the improper fraction: -5/7a = 45/28

Step 3: To solve for "a," we need to get rid of the fraction on the left side. We can do this by multiplying both sides of the equation by the reciprocal of (-5/7), which is (-7/5):

(-7/5) * (-5/7a) = (-7/5) * (45/28)

Step 4: Simplify the equation: a = (-7/5) * (45/28)

Step 5: Multiply the fractions: a = (-7 * 45) / (5 * 28)

Step 6: Calculate the result: a = -315 / 140

Step 7: Reduce the fraction (if possible): a = -9/4

So the value of "a" is -9/4 or -2.25 (in decimal form).
