Answer 2

Given

45 cookies will feed 15 students

We Find

How many cookies 30 students feed

How to Find ?

We Find with two methods are given below

According to the question

There are Two Method to Solve :-

❍ 1st Method

We solve by ratio and proporation,So :-

$\sf {\frac{45}{15} = \frac{X}{30}}$

$\sf { X = \frac{45 × 30}{15}}$

$\sf { X = \frac{1350}{15}}$

$\sf { X = \cancel\frac{1350}{15}}$

$\sf { X = 90}$

❍ 2nd Method

We knows, for every 15 students you need 45 cookies. There are 2 groups of 15 students in 30 :-

(15x2=30)

So, that means you need 2 groups of 45 cookies because you have 2 groups of 15 students.

SO the answer is 45 x 2 = 90 cookies

Hence , Required answer is 90 cookies.
