How to divide fractions

Dmitry [639]

To divide fractions, firstly, you need to turn the 2nd fraction upside down. For example, 3/8 divided by 3/4 would be 3/8 divided by 4/3. After you have flipped the second fraction, you multiply them - 3*4 = 12. 8*3 = 24 so the answer would be 12/24. Which then could be cancelled down to 1/2. I hope this makes sense!!

Answer:

Each pizza have 8 slices.

Step-by-step explanation:

Given:

At a party to celebrate a successful school play, the drama club bought 9 large pizzas.

Each pizza had s slices.

All together, there were 72 slices of pizza for the club to share.

Now, to find slices each pizza have.

Number of slices each pizza have = $s.$

Number of slices of pizza altogether = $72.$

Total number of pizza = $9.$

Now, to write an equation of this situation:

$9\times s=72$

$9s=72.$

So, to get the slices each pizza have we solve the above equation:

$9s=72$

Dividing both sides by 9 we get:

$s=8.$

Therefore, each pizza have 8 slices.

What happens to the total mass of the atoms involved in a chemical reaction

Daniel [21]

There won't be any change in the total mass of the atoms involved in a chemical reaction. According to the law of conservation of mass; it states that mass can neither be created nor destroyed in a chemical reaction. So, when atoms participate in a chemical reaction they might displace with other reactants but the total mass will remain the same.

Find the 93rd term of the arithmetic sequence -11, -7, -3

alina1380 [7]

Answer:

357

Step-by-step explanation:

hello :

note : the n th term of an arithmetic sequence is :

An =A1+(n-1)d ....a common difference is : d and A1 the first term

in this exercice : d = -3-(-7) =-7-(-11) = 4 A1 = -11

when : n =93 you have the 93rd term A93

so : A93 = -11 +(93-1)(4)

A93 = 357
