Question

PLEASE HELP Write an expression and solve it with the given values of the letters: b There are x candies in a bag. 4/9 of all the candies are chocolates. How many candies which are not chocolates are in the bag? (x=36)

Answer 1

20

Explanation:

Total: x

Chocolate: 4/9 of x = 4x/9

Not chocolate: total - chocolate

x - 4x/9

x(1 - 4/9)

x(9-4)/9

x(5/9)

5x/9

x = 36

5x/9 = 5×36/9 = 5×4 = 20

Answer 2

5/9x

20 candies

Explanation:

There are a total of x candies. We know that 4/9 of them are chocolates. Write this into a mathematical expression:

- "of" always indicates multiplication. So, if we have 4/9 "of" all the candies, we have 4/9 * something

That "something" is the total candies, of which there are x:

4/9 * x

We want how many candies are not chocolates, so we need to subtract this number (4/9 * x) from the total x:

x - 4/9 * x = 5/9x

Now, let's plug 36 in for x:

5/9 * 36 = 20 candies
