The product is the result of multiplication
so the product of 83 and x is : 83x
        
                    
             
        
        
        
Answer:
Imagine that the number that we are looking for is x
We know that: 
x/5 - 78 = 9
x/5         = 9 + 78
x/5         = 87
x             = 87 . 5 = 435
So the number we need is 435

Answer:
1) 5 : 7 : 8.75
2) Happy = 168 .    Juma = 210
3) Rima = 17800 .     Happy = 24920 .    Juma = 31150
Step-by-step explanation:
1) 5 : 7 : 8.75
Ratio Rima to Happy = 5:7
Ratio Happy to Juma = 4:5
7/4 = 1.75
1.75 x 5 = 8.75
Ratio = 5 : 7 : 8.75
2) Happy = 168 .     Juma = 210
Ratio = 5 : 7 : 8.5
120 / 5 = 24
Happy = 24 x 7 = 168
Juma = 24 x 8.75 = 210
3)17800 : 24920 : 31150
5 + 7 + 8.75 = 20.75
73870 / 20.75 = 3560
3560 * 5 = 17800 = Rima
3560 * 7 = 24920 = Happy
3560 * 8.75 = 31150 = Juma
