List four rational number between -4/5 and -2/3

Mathematics
1 answer:
MatroZZZ [7]3 years ago
4 0

Answer:

-31/45, -32/45, -33/45, -34/45, and -35/45

Step-by-step explanation:

Rational numbers are any number that can be written as a ratio of two integers.

First, find the common denominator using the least common multiple (LCM).

The LCM of 3 and 5 is 15.  So the fractions can be written as:

-12/15 and -10/15

If we keep the denominator 15, then only one rational number can be written between these two: -11/15.  We need to find four rational numbers.  So instead, let's use a denominator of 45.  The fractions become:

-36/45 and -30/45

Now we can write five rational numbers between those:

-31/45, -32/45, -33/45, -34/45, and -35/45.

Choose any 4 that you like.

I need help solving this
Stolb23 [73]

Step-by-step explanation:

So in the equation given, y = 2x - 3

you substitute x for whats given in the table in the x column.

Example

In the graph the first number under the x colum is -1.

y = 2x - 3 in the equation you take out x and put -1.

So now the equation becomes y = 2 × -1 - 3.

Using bedmas to solve the question you should get -5

Which now means y = -5

To plot the point now x would be -1 and y would be -5 (-1, -5)

Same thing for the second number in the x Column.

y = 2 × 1 - 3 which equals -1

To plot it

x = 1 y = -1. (1, -1)

And for the last number 3.

Agai. You substitute x for 3 which makes the equation y = 2 × 3 - 3

this gives you 3 and to plot it

x would be 3 and y would be 3
