Answer 1

x (Total number of chocolates) = 27

6 milk chocolates

Explanation:

1)
`(7)/(9) * x = 21`

2)
`(9)/(7) *`
`(7)/(9) * x = 21`
`* (9)/(7)`

∧ The fraction gets cross-multiplied and gets removed. 21 is then multiplied by 9/7

3)
`x = 21 * (9)/(7)`

4)
`7 * x =21 *( (9)/(7) * (7)/(1) )`

∧ The 9 / 7 gets multiplied by 7 / 1 to become 9. 7 is then multiplied by x

5)
`7x = 21 * 9`

6) Simplify 21 * 9 to 189

7)
`7x = 189, becomes, (7x)/(7) = (189)/(7)`

8) Simplify to
`x = 27` , where x = total number of chocolates

9)
`27 - 21 = 6` milk chocolates

Answer 2

27

Explanation:

7x3=21

if that's 3 that's means 9x3 is the answer and its 27
