How do I convert 82.1, 7.3, 9.3 in a fraction form

nalin [4]

Answer:

Step-by-step explanation:

82.1 = 82 1/10 (thats 82 and 1/10) or 821/10 (if you dont want a mixed number)

7.3 = 7 3/10 or 73/10

9.3 = 9 3/10 or 93/10

if there is 1 number to the right of the decimal, put that number over 10....not the whole number, just the number to the right of the decimal. Leave the number to the left of the decimal alone.

if there were 2 numbers to the right of the decimal, then put those two numbers over 100.

example :

3.43 = 3 43/100

2.76 = 2 76/100

if there were 3 numbers to the right of the decimal, put those 3 numbers over 1000

example :

2.347 = 2 347/1000

3.679 = 3 679/1000

you understand ?

Dwight and Walt are building model cars. Dwight builds 7 fewer models than 4 times the number Walt builds.Dwight builds at most

romanna [79]

$4x-7\leq 9$ inequality could be used to find the number of models Walt builds. Correct option B).

<u>Step-by-step explanation:</u>

Here we have , Dwight and Walt are building model cars. Dwight builds 7 fewer models than 4 times the number Walt builds.Dwight builds at most 9 models. We need to find Which inequality could be used to find the number of models Walt builds . Let's find out:

Let the the number Walt builds is x , So Dwight builds 7 fewer models than 4 times the number Walt builds i.e.

⇒ $4x-7$

But , according to question Dwight builds at most 9 models i.e.

⇒ $4x-7\leq 9$

⇒ $4x\leq 16$

⇒ $\frac{4x}{4}\leq \frac{16}{4}$

⇒ $x\leq 4$

Therefore , $4x-7\leq 9$ inequality could be used to find the number of models Walt builds which is Dwight builds at most 9 and Walt builds at most 4 .

1. Thom has a scale model of his car. The

MariettaO [177]

$x =\frac{4}{3}inch$ is the size in wheels on the scale model .

<u>Step-by-step explanation:</u>

Correct Question : Tom has a scale model of his car. The scale factor is 1 : 12. If the actual car has 16-inch wheels, what size are the wheels on the scale model?

We have , The scale factor is 1 : 12. We need to find If the actual car has 16-inch wheels, what size are the wheels on the scale model .Let's find out:

Ratio of size of wheels to actual size of wheels is 1:12 , but actual car has 16-inch wheels So ,

⇒ $\frac{1}{12} = \frac{x}{16}$ { x is size of wheel in scale model }
