Question

Indicated operation of 7 over 15 divided by 28 over negative 30

Answer 1

-1/2

Explanation:

To perform the indicated operation of 7/15 ÷ 28/(-30), we need to remember that division is the same as multiplication by the reciprocal of the divisor.

Step 1: Find the reciprocal of 28/(-30):

Reciprocal of 28/(-30) = (-30)/28 = -15/14

Step 2: Now, the division becomes multiplication:

7/15 ÷ 28/(-30) = 7/15 * (-15/14)

Step 3: Simplify the multiplication:

7/15 * (-15/14) = (7 * (-15)) / (15 * 14)

Step 4: Calculate the result:

(-105) / 210 = -1/2

So, 7/15 ÷ 28/(-30) is equal to -1/2.
