Question

700 is 2 parts in the ratio 3:2, how much would 3 parts be?

Answer 1

1050

Step-by-step explanation:

If 700 is 2 parts, then

1 part = 700 ÷ 2 = 350

So 3 parts = 3 x 350 = 1050

Algebraically:

3 : 2 = x : 700

⇒
`\frac32=(x)/(700)`

⇒ 3 x 700 = 2
`x`

⇒ 2100 = 2
`x`

⇒
`x` = 1050

Answer 2

3 parts will be 420

Step-by-step explanation:

total ratio: 3 + 2 = 5

5 ➳ 700

1 ➳ 700/5

1 ➳ 140

solve for 3 : 2

3 ➳ 140 * 3 = 420

2 ➳ 140 * 2 = 280
