Answer:


r=4(3)/(8)

Explanation:

Given the following question:


4(5)/(8) +r=9

Rewrite the expression to find the value of r:


9-4(5)/(8)

Subtract by finding the common denominator:

9-4(5)/(8)

9=(9)/(1)

4(5)/(8) =8*4=32+5=37=(37)/(8)

(9)/(1) -(37)/(8)

(9)/(1) *8=(72)/(8)

(37)/(8) *1=(37)/(8)

(72)/(8) -(37)/(8)

72-37=35

=(35)/(8)

(35)/(8) =35/8=4(3)/(8)

r=4(3)/(8)

4(5)/(8) +4(3)/(8) =9

Hope this helps.
