How do you do multiplication and division?
cluponka [151]

Answer:

See below.

Step-by-step explanation:

Multiplication:

x times 2

x times 2 would be x+x

Basically for each one number, you add the other one by. For example:

3 times 2 : 2+2+2 or 3+3

4 times 7: 4+4+4+4+4+4+4 or 7+7+7+7

Division:

x divided by 2

Division is how many groups of a number can you fit into the first one. For example:

4 divided by 2= Two groups of two can fit into four. (2+2)

6 divided by 3= Two groups of three can fit into six. (3+3)

A company produces three combinations of mixed vegetables that sell in​ 1-kg packages. Italian style combines 0.4 kg of​ zucchin
Llana [10]

Answer:

Italian style = 18,000 packages

French style = 14,000 packages

Oriental style = 53,000 packages

Step-by-step explanation:

See the attached figure to represent the question

let the number of packages of Italian style = x

let the number of packages of French style = y

let the number of packages of Oriental style = z

By using the figure we can make the following equations:

0.4x + 0 * y + 0.2z = 17,800

0.3x + 0.5y + 0.3z = 28,300

0.3x + 0.5y + 0.5z = 38,900

Solving the 3 equations together to find x , y and z

Using the calculator:

x = 18,000 ⇒ Italian style packages

y = 14,000 ⇒ French style packages

z = 53,000 ⇒ Oriental style packages

After going on a diet,Amy finds that her weight has decreased by 25%.If her weight now is 75kg how much does her weight before?​
Rainbow [258]

Answer:

Her weight before was 100kg.

Step-by-step explanation:

This question can be solved using a rule of three.

Amy finds that her weight has decreased by 25%

So her weight is 100-25 = 75% = 0.75 of the original amount(what it was before).

Her current weight is 75kg.

Her previous weight was x, which is 100% = 1.

So

75 - 0.75

x - 1

0.75x = 75

x = \frac{75}{0.75}

x = 100

Her weight before was 100kg.
