[The First correct answers will be marked as the Brainiest]

Answer 1

Answer:

• 90 articles is the required answer

Step-by-step explanation:

According to the Question

It is given that,

• 25 identical articles weigh 275g

we have to calculate how many articles 990g

Firstly we calculate the weigh of 1 identical article.

Weigh of 1 article = Given Weigh/No.of article

by putting the value we get

⇢ Weigh of 1 article = 275/25

⇢ Weigh of 1 article = 11g

Now, calculating the No. of articles .

No. of Articles = Given Weigh/Weigh of 1 article

by putting the value we get

⇢ No. of articles = 990/11

⇢ No. of articles = 90

• Hence , the number of articles are 90 .

Answer 2

$\large\underline{\bf{Answer \rightarrow }}$

$\large\underline{\bf{ \implies 90 \: articles}}$

$\large\underline{\bf{Solution \implies}}$

$\large\underline{\bf{Question \rightarrow}}$

$\small\underline{\bf{If \: 25 \: identical \: articles \: weigh}}$

$\small\underline{\bf{275g.Find \: how \: many \: articles \: 990g}}$

$\large\underline{\bf{formula \:used }}$

$\large\underline{\bf{ \frac{x_{1}}{ y_{1} } = \frac{ x_{1}}{y_{2} } }}$

$\large\underline{\bf{putting \: values}}$

$\large\underline{\bf{ \frac{25}{x} = \frac{275}{990} }}$

$\large\underline{\bf{on \: cross \: multiplication}}$

$\large\underline{\bf{990 \times 25 = 275y}}$

$\large\underline{\bf{cross \: multiplying}}$

$\large\underline{\bf{ \frac{990g \times 25}{275g} = y }}$

$\large\underline{\bf{90 \: articles = y}}$

$\small\underline{\bf{hence \: 90 \: articles \: are \: required.}}$
