Question

How is it 840g plsss help!

Answer 1

Explanation:

Let's say first piece is x. First and third ratio is 1:4 so it would be

4x - x = 360

3x = 360

x = 120 Third piece is 120g. Now we just multiply the rest.

2 × 120 = 240g

4 × 120 = 480g, total 840g

Answer 2

840 g

Explanation:

Ratio:

Ratio of weight of 3 pieces = 1 : 2 : 4

Weight of 3 pieces = x , 2x , 4x

Weight of third piece - weight of first piece = 360 g

4x - x = 360

3x = 360

Divide both sides by 3,

x = 360÷ 3

x = 120 g

Weight of first piece = x = 120 g

Weight of second piece = 2x = 2*120 = 240g

Weight of third piece = 4x = 4 *120 = 480 g

Weight of the whole cake = 120 + 240 + 480

= 840 g
