Well, you would istribute
using
a(b+c)=ab+ac
so
3(g+5)=3(g)+3(5)=3g+15
2(3g-6)=2(3g)+2(-6)=6g-12
now we gots
3g+15+6g-12
using commutative, we can arrange and group like terms because
a+b=b+a
so
3g+6g+15-12
add
9g+3
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".

Answer:
1.A. 88.89
2.B.6.3%
3.C.64.92%
Step-by-step explanation:
1.
to covert it into percentage multiply it with 100
then it becomes 88.888
rounding off to the nearest hundred it becomes 88.89
2. to convert into percentage multiply it with 100
therefore 0.063×100=6.3%
3. to find percentage
%= (no of students using mobile / total no of students )× 100
= 
×100
=64.918
Rounding off to nearest hundred it becomes 64.92%
