Expand 7/4 (8h+3).

To expand 7/4(8h+3), we distribute the 7/4 to both terms inside the parentheses:

(7/4)(8h) + (7/4)(3)

This simplifies to:

(7/4)(8h) + (7/4)(3)
= (56h/4) + (21/4)

To simplify further, we can combine like terms:

(56h/4) + (21/4)
= (56h + 21)/4

Therefore, the expanded form of 7/4(8h+3) is (56h + 21)/4.
