Question

Please help me out, hopefully it’s clear, very urgent. Thanks

Answer 1

We know that:

`\frac{\tex\text{Diamonds}}{\text{Emeralds}} = (3)/(4)`

`\text{Emeralds} = 16`

Substitute the amount of emeralds in the ratio to find the amount of diamonds.

`\frac{\tex\text{Diamonds}}{16} = (3)/(4)`

`\tex\text{Diamonds} = (3 * 16)/(4)`

`\tex\text{Diamonds} = (48)/(4) = 12`

Thus, there were 12 diamonds.

Answer 2

(a)

girls to boys → 2 : 1

2 → 24

1 → 12

There are total 12 boys.

(b)

diamonds to emeralds → 3 : 4

4 → 16

1 → 4

3 → 12

There are 12 diamonds.
