Step-by-step explanation:

For example, the reciprocal of ¾ is 4/3.

Division of Fractions

Find the reciprocal of 3 ¾

The reciprocal of 3 ¾ is 4/15.

Division of Fractions Reciprocal

I. Division of a fraction by a whole number:

For example:

(i) Divide 3/5 by 12

Solution:

3/5 ÷ 12

= 3/5 ÷ 12/1

= 3/5 × 1/12

= (3 × 1)/(5 × 12)

= 3/60

= 1/20

Step I: Find the reciprocal of the whole number and multiply with the fractional number as usual.

Step II: Express the product in its lowest terms.

(ii) Solve: 5/7 ÷ 10

= 5/7 ÷ 10/1

= 5/7 × 1/10

= (5 × 1)/(7 × 10)

= 5/70

Step I: Find the reciprocal of the whole number and multiply with the fractional number as usual.

Step II: Express the product in its lowest terms.

II. Division of a fractional number by a fractional number:

For example:

(i) Divide 7/8 by 1/5

Solution:

7/8 ÷ 1/5

= 7/8 × 5/1

= (7 × 5)/(8 × 1)

= 35/8

= 4 3/8

Step I: Find reciprocal of 1/5.

Step II: Multiply 7/8 by it.

Step III: Express the product in its simplest form.

(ii) Divide: 5/9 ÷ 10/18

Solution:

5/9 ÷ 10/18

= 5/9 × 18/10

= (5 × 18)/(9 × 10)

= 90/90

= 1

Step I: Find reciprocal of 1/5.

Step II: Multiply 7/8 by it.

Step III: Express the product in its simplest form.

An appliance store sells lamps at $95.00 for two. A department store sells similar lamps at five for $250.00. Which store sells

snow_tiger [21]

Answer:

Appliance store has better rate than department store.

Step-by-step explanation:

Appliance store gives 2 for $95

So price of 1 will be = 95/2 = $47.5

Department store sells 5 for $250

So price of 1 will be = $250/5 = $ 50

So as a buyer we are in profit when buy from appliance store because we are at a profit of $2.5 per lamp.

I hope it will help you!

The sum of a number and its reciprocal is 61 30 . Find the numbers.

Maksim231197 [3]

Let's say the number is hmmm "a", its reciprocal would then be 1/a
thus $\bf a+\cfrac{1}{a}=\cfrac{61}{30}$

solve for "a"

Sam said the square root of a rational number must be a rational number. Jenna disagreed. She said that it is possible that the

ratelena [41]

Jenna is correct because the square root of a rational number can still be irrational.

Take for example the square root of 2. It is an irrational number than goes 1.41421...

If you multiply just the first however many digits of the result by itself, you will never end up with a perfect 2, because the square root is irrational.

[Right Triangles Only] Pythagorean Theorem:
$\displaystyle a^2 + b^2 = c^2$

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Define

Identify given variables.

a = 30

b = 3

c = x

Step 2: Find x

Let's solve for the general equation that allows us to find the hypotenuse:

[Pythagorean Theorem] Square root both sides [Equality Property]:
$\displaystyle \begin{aligned}a^2 + b^2 = c^2 \rightarrow c = \sqrt{a^2 + b^2}\end{aligned}$

Now that we have the formula to solve for the hypotenuse, let's figure out what x is equal to:

[Equation] Substitute in variables:
$\displaystyle \begin{aligned}c & = \sqrt{a^2 + b^2} \\x & = \sqrt{30^2 + 3^2}\end{aligned}$
Evaluate:
$\displaystyle \begin{aligned}c & = \sqrt{a^2 + b^2} \\x & = \sqrt{30^2 + 3^2} \\& = \boxed{ \sqrt{909} } \\\end{aligned}$

∴ the hypotenuse length x is equal to √909 and the number under the square root, our answer, is equal to 909.
