Answer:

5 5/8 = (5*8)+5)/8 = 45/8

2/5 * 45/8 = (2*45)/(5*8)= 90/40 = 9/4

Answer:


\sf (9)/(4) \textsf{ or } 2 (1)/(4)

Explanation:

The distributive property of multiplication over addition states that for any numbers a, b, and c, the following equation is true:


\sf a(b + c) = ab + ac

In other words, when we multiply a number by a sum of two other numbers, we can distribute the multiplication to each of the two numbers and add the products together.

To use the distributive property to simplify the expression
\sf (2)/(5) * 5 ( 5)/(8), we can first rewrite it and distribute and simplify each term and add the two terms:


\begin{aligned} (2)/(5) * 5 ( 5)/(8) & = (2)/(5) * \left(5 + (5)/(8)\right) \\\\ &= \frac{2}{\cancel{5}} * \cancel{5} + \frac{2}{\cancel{5}} * \frac{\cancel{5}}{8} \\\\ &= 2 + \frac{\cancel{2}}{\cancel{2}\cdot 4 } \\\\ &= 2 + (1)/(4) \\\\ &= (2* 4 + 1)/(4) \\\\ &= (9)/(4) \textsf{ or } 2 (1)/(4) \end{aligned}

Therefore, the value of the expression using the distributive property is:


\sf (9)/(4) \textsf{ or } 2 (1)/(4)
