The 875 times smaller is 4 x 10−7 than 3.5 x 10−4.
<h3>What is the arithmetic operator?</h3>
Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given the two quantities 4 x 10−7 and 3.5 x 10−4
Now, if we divide this then
⇒ (3.5 x 10−4)/(4 x 10−7)
⇒ (35/40) × 10³
⇒ 875
Hence "The 875 times smaller is 4 x 10−7 than 3.5 x 10−4".

Step-by-step explanation:
Answer:
Rhea's estimation is unreasonable.
Step-by-step explanation:
Identify what you know:
1) Rhea calculates that she can write 1.25 pages every 2 hours
2) Rhea is calculating how long it would take her to write 6 pages.
Using Rhea's initial calculation, we can figure out roughly, how long it would take her to finish 6 pages.
First we need to divide 6 by 1.25, to figure out how many "2 hour" periods it would take Rhea.
6/1.25 = 4.8
4.8 x 2 = 9.6
It would take Rhea roughly 9.6 hours to finish 6 pages, which is 3.6 hours more than her original estimation. Thus, her estimate is unreasonable.
