What is 2 2/3 dived by 1 1/4 equal

1 answer:

8 0

22 1/2)/(1/4)=?

22 1/2= 23/2

then we get:

(23/2)/(1/4)=?

we can flip the 1/4 to 4/1 and multiply instead of dividing so we get:

(23/2)X(4/1)=?

multiply numerators and denominators:

(23/2)X(4/1)=92/2

simify:

=46

Choose the best description for the real number 34 over 3.

harkovskaia [24]

Answer:

The answer is C

Step-by-step explanation:

First of all let's eliminate the answers that do not make sense. For A. numbers are NOT irrational because they are a fraction. Numbers are also not irrational because they are a repeating number. C and D are both correct as fractions and terminating decimals are both rational numbers.

34/3≈11.33333333

By using a certain formula you can convert repeating decimals to a fraction. But most people know that .3333333 is 1/3. This gives us 11 1/3 as our answer. So what does it match? It is not a terminating decimal. It repeats but can be written as a fraction. Therefore our answer is C) Rational, because it is a fraction.

Multiply

27x + 72 - 12x - 63

Combined like terms

27x - 12x = 15x 72 - 63 = 9

Imaginary Root i = √-1

Step-by-step explanation:

Step 1: Define

Identify

2x² + x + 67 = 0

a = 2

b = 1

c = 67

Step 2: Solve for x

Substitute in variables [Quadratic Formula]: $\displaystyle x=\frac{-1 \pm \sqrt{1^2-4(2)(67)}}{2(1)}$
Multiply: $\displaystyle x=\frac{-1 \pm \sqrt{1^2-4(2)(67)}}{2}$
[√Radical] Evaluate exponents: $\displaystyle x=\frac{-1 \pm \sqrt{1-4(2)(67)}}{2}$
[√Radical] Multiply: $\displaystyle x=\frac{-1 \pm \sqrt{1-536}}{2}$
[√Radical] Subtract: $\displaystyle x=\frac{-1 \pm \sqrt{-535}}{2}$
