£360 is shared between Abby, ben, chloe and denesh. the ratio of the amount abby gets to the amount that ben gets is 2:7. chloe

Gwar [14]

Answer:

$210$ £

Step-by-step explanation:

Let amount that abby gets $=x$

Given that $\frac{Amount\ of\ abby}{Amount\ of\ Ben} =\frac{2}{7}$

$Amount\ of\ ben=\frac{7}{2}\times Amount\ of\ abby\\ =\frac{7}{2}\ x$

Amount of chole + amount of Danesh $=1.5\times$ of abby

$=1.5 \ x$

$x +\frac{7}{2} \ x + 1.5 \ x =360\\\\6x=360\\\\x=\frac{360}{6}\\\\x=60$

$Amount\ of\ Ben =\frac{7}{2}\ x = \frac{7}{2} \times 60\\\\=7\times 30\\\\=210$

Please help me :) please

Answer:

In bold.

Step-by-step explanation:

6/6 = 9/a

So a = 9.

6/c = a/4.5

6/c = 9/4.5 = 2

So c = 3.

By similar triangles:

d/5 = 6/ (6+6+3)

d/5 = 6/15 = 2/5

So d = 2.

Also by similar triangles

b/5 = 12/15 = 4/5

So b = 4.
