£440 is divided between David, Mark & Henry so that David gets twice as much as Mark, and Mark gets three times as much as H

Lesechka [4]

Mark received £ 132

Solution:

Given that £440 is divided between David, Mark & Henry

Let "d" be the share of david

Let "m" be the share of mark

Let "h" be the share of henry

Total amount is 440

Therefore,

share of david + share of mark + share of henry = 440

d + m + h = 440 ------- eqn 1

David gets twice as much as Mark

d = 2m ----- eqn 2

Mark gets three times as much as Henry

m = 3h

$h = \frac{m}{3}$ ------ eqn 3

Substitute eqn 2 and eqn 3 in eqn 1

$2m + m + \frac{m}{3} = 440\\\\\frac{6m + 3m + m}{3} = 440\\\\10m = 1320\\\\m = 132$

Thus Mark received £ 132

What's the difference between two whole number 1/2 percent of 36 and 30% of 10

AlexFokin [52]

Here, we proceed step by step, to obtain our answer,

$\frac{1}{2}$ % of 36 can be written as ,

0.5 % of 36 , which means,

100 % refers to 36, then

0.5 % refers to what, thus, by cross multiplication we get,

0.5 % of 36 = $\frac{0.5 X 36}{100}$ = 0.18 ___(1), which can be expressed in whole numbers as 0.

Now, 30 % of 10 means,

100 % refers to 10, then

30 % refers to what, thus, by cross multiplication we get,

30 % of 10 = $\frac{30 X 10}{100}$ = 3 __(2)

From equations (1) and (2),

the whole numbers that we obtain are 0 and 3, respectively,

Thus the difference between these two whole numbers is,

= 3 - 0 = 3.
