A(4 7/8)=20

To solve the equation A(4 7/8) = 20, we need to first convert the mixed number 4 7/8 to an improper fraction:

4 7/8 = 4 + 7/8 = 32/8 + 7/8 = 39/8

Now, the equation becomes A(39/8) = 20. To solve for A, we need to divide both sides by 39/8:

A = 20 / (39/8) A = 20 * (8/39) A = 160/39

Therefore, the value of A is 160/39.
