Step-by-step explanation:
Phrase : "the product of 19 and a number"
The product of two numbers a and b can be written as a x b =ab
<u>To find Mathematical expression
</u>
Let A be a number,
The product of number with 19 can be written as
19 x A = 19A
Therefore the given phrase "the product of 19 and a number" as a mathematical expression =19A
Simplifying, we get y -32 = 9x/5 or equal to y = 9/5 x + 32 where x is degrees Celsius and y is degrees Fahrenheit.
Do you mean the 2/3, 4/5,2/8 etc.are fractions? Or dividing each number? If so for dividing each number the answer is 0.9. For fractions the answer is 7 and 1/2. Hope I helped!
