The answer would be
In 1.23, we know that 1 is a whole number and .23 is part of a whole, so it is a fraction.
.23 can be written as because the decimal is till the hundredths place.
We cannot simplify any further so we leave it as is.
The answer would then be.
Answer: 1.23 pounds= pounds.
Step-by-step explanation:
Given number = 1.23
Convert it into fraction
here, Numerator=123
Denominator=100
To convert the fraction in mixed fraction , divide the numerator by denominator ,we get
Divisor=100
Quotient=1
Remainder=23
Thus
Therefore, 1.23 pounds= pounds.

x,y - the numbers
one positive number is 5 less than twice a second number
(1) x - 5 = 2y
their product is 117
(2) xy = 117
(1) x - 5 = 2y add 5 to both sides
x = 2y + 5 substitute it to (2)
(2y + 5)y = 117 use distributive property
(2y)(y) + (5)(y) = 117
2y² + 5y = 117 subtract 117 from both sides
2y² + 5y - 117 = 0
2y² + 18y - 13y - 117 = 0
2y(y + 9) - 13(y + 9) = 0
(y + 9)(2y - 13) = 0 ↔ y + 9 = 0 ∨ 2y - 13 = 0
y + 9 = 0 subtract 9 from both sides
y = -9
2y - 13 = 0 add 13 to both sides
2y = 13 divide both sides by 2
y = 6.5
substitute the values of y to (1)
x = 2(-9) + 5 = -18 + 5 = -13 < 0
x = 2(6.5) + 5 = 13 + 5 = 18
Answer: x = 18 and y = 6.5

The numbers are which multiplies to 4 and adds to 2.
Let x and y be two numbers which is multiplied to 4 and adds to 2.
So, x×y = 4...(1)
x + y=2...(2)
So, y=2-x
Put y=2-x in (1), we get
x×(2-x ) = 4
Therefore numbers are which multiplies to 4 and adds to 2.

By decomposing the figure in simpler ones, we conclude that its area is 9 square units.
How to get the area of the figure?
Let's read the figure from the top.
First, we can see in the top two triangles that have an area of half a square unit, then adding these two we have one square unit.
Below that, there are 4 square units inside the figure.
On the left and right sides, there are triangles of base of 1 unit and height of 2 units, then each of these triangles has an area of:
a = 1*2/2 = 1 square unit
And we have 2 of these triangles, so the total area is 2 square units.
Finally, on the bottom we can see 4 triangles like in the top part, we know that each one of these measure 0.5 square units, then the 4 add up to 2 square units.
Adding all the areas above, we see that the total area is:
A = (1 + 4 + 2 + 2) square units = 9 square units.
So the correct option is C
