Renaldo will write 3/20 as a decimal. which of the following methods should he use?
1. multiply the fraction by 5/5 to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
2.multiply the fraction by 1/5 to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
3. multiply the fraction by 33.3/33.3 to get a numerator of 100 and then write the denominator as hundredths using a decimal point.
4. multiply the fraction by 33.3 to get a numerator of 100 and then write the denominator as hundredths using a decimal point.

ANSWER

1. Multiply the fraction by 5/5 to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

EXPLANATION

Renaldo wants to write

as a decimal.

He needs a denominator of 100, so he can multiply by

to obtain:

This will be

He can now obtain the decimal equivalent as

The correct choice is option 1.

1. Multiply the fraction by 5/5 to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

Step-by-step explanation:

Renaldo must use a method that does not alter the value of the original fraction. This means that by multiplying the fraction by a number, the result obtained remains the same as the initial number.

Then the fraction must be multiplied by the same number in the denominator and the numerator. For example:

If we multiply the result is:

To write this fraction in decimal form, we move the comma 2 digits to the left in the following way:

15.0 --------> 0.15.

Then

The answer is Option 1.

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

a.   we have two

lines:   y = 4-x   and  

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b.   4-x = 8-x^-1

  x           4-x       8-x^-1

-3           7        

8.33

-2           6         8.5

-1           5         9

  0           4        

-

  1           3        

7

  2           2        

7.5

  3           1         7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:  

x=-4.236

y = 4-x   = 4 – (-4.236)

= 8.236

y = 8-x^-1 =   .236)^-1

= 8.236

x=0.236

  y = 4-x   = 4 – (0.236) = 3.764

y = 8-x^-1 =   8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c.   to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x   and   y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines.   the

solution is, as stated, the point where the two lines cross on the graph.
