3 of 6 Sushil, Natasha & Fiona share some money in the ratio 1:4:2
In total, Sushil and Fiona receive £39
How much does Natasha get?

Amount got by Natasha = £52

Step-by-step explanation:

Given that:

Ratio of Sushil, Natasha and Fiona's share = 1:4:2

Amount of money received by Sushil and Fiona = £39

Let,

x be the number of times.

x+2x = 39

3x = 39

Dividing both sides by 3

Share of Natasha = 4x = 4(13) = £52

Hence,

Amount got by Natasha = £52

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
