Question

plz solve it asap plz​

Answer 1

The ratio of muffins to the cookies and 1:2 are proportional ratios.

The number of the muffins is 15, so let the number of cookies be x.

$1:2=15:x$

The products of the means and extremes are equal.

$1\times x=2\times 15$, so $x=30$

So the number of the cookies is 30.

Why do two products(means, extremes) equal?

We have $a:b=c:d$ for the example.

Fractions are also used to compare quantities. In fact, fractions are ratios.

The ratios are converted into fractions.

$\dfrac{a}{b} =\dfrac{c}{d}$

We multiply the same number on both sides to keep them equal.

$bd\times\dfrac{a}{b} =bd\times\dfrac{c}{d}$

The denominator cancel out so we get $ad=bc$. And $ad$ is the extremes, $bc$ is the means!

Answer 2

Answer:

Given :-

• Ratio of muffins : cookies = 1:2
• Total muffins = 15

To Find :-

Cookies bake

Solution :-

Let the cookies be a

Here,

It is the concept of Ratio and Proportion. In the question we have to find muffins. By using the concept of,

Product of means = Product of extremes

$\sf \: 1 : 2 = 15 : x$

$\sf \: 1 \times x = 2 \times 15$

$\sf \: x = 30$

Hence :-

Numbers of cookies = 30
