Answer 1

Answer:

40 marbles

Step-by-step explanation:

because for every one blue marble there are two white marbels so if u time 2 by 20 it's 40

Answer 2

There are 40 white marbles in Simran's bag.

Solution:

Assume number of blue marbles as B and the number of white marbles as W

Given, ratio of blue marbles to white marbles i.e. B:W is $\bold{1:2}$

Number of blue marbles B = 20

To find, number of white marbles W

The given ratio can be written as $\frac{1}{2}$ and is equal to the ratio $\bold{B:W \rightarrow 20:W}$

Therefore, $\bold{\frac{1}{2} = \frac{20}{W}}$

On bringing the common terms together we get,

$\bold{W=\frac{20\times2}{1} \rightarrow \frac{40}{1} \rightarrow 40}$

Hence the value of x is 40.
