for any fraction a/b, the decimal format of it is just a ÷ b.
A)
is the number rational?
well, a rational number is one we can write as a ration or fraction, well clearly is a fraction so it is rational.
B)
can it be written as a repeating/recurring decimal? well, 9/20 is 0.45, so -9/20 is -0.45, no repeating decimal like 0.454545......... , just a plain vanilla -0.45, so nope.
C)
is it less than -0.4?
well, let's recall that for the negative side on the number line, the closer to 0, the larger the number, so then -1,000,000 is much smaller than -1, because -1 is closer to 0.
who is closer -0.4 or -0.45?
|--------------------- -0.45 -------- -0.40 ------------------- 0 --------------- 1 -------------------|
so, -0.45 is farther from 0, and therefore is smaller than -0.4, so yes.

Answer:
0.318
Step-by-step explanation:
on division with 10, the value reduces.... decimal moves forward
on multiplication, the value increases decimal moves backward....

Answer: Celine, 4092 ml
Step-by-step explanation:
Given
1 bottle contains 341 ml Juice
Celine buys 2 cases of 24 bottles i.e. a total of 48 bottles
Nicole buys 3 cases of 12 bottles i.e. a total of 36 bottles
Amount of Juice Celine has
Amount of Juice Nicole has

Thus, Celine has more juice than Nicole

Celine has 4092 ml more than Nicole
Let A(4,12) and B(6,18)
RATE OF CHANGE = m = (y₂ - y₁) / (x₂ - x₁) = (18-12)/ (6-4)
m= 6/2 or m = 3
