Two brothers are sharing a certain sum of money in the ratio 2/3 : 3/5, if the largest share was Gh¢500.00. How much was shared
lina2011 [118]

Given:

Two brothers are sharing a certain sum of money in the ratio \dfrac{2}{3}:\dfrac{3}{5}.

The largest share was Gh¢500.00.

To find:

The total amount shared between them.

Solution:

It is given that, two brothers are sharing a certain sum of money in the ratio \dfrac{2}{3}:\dfrac{3}{5}.

First we need to make the denominators common.

Ratio=\dfrac{2\times 5}{3\times 5}:\dfrac{3\times 3}{5\times 3}

Ratio=\dfrac{10}{15}:\dfrac{9}{15}

Ratio=10:9

So, the two brothers are sharing a certain sum of money in the ratio 10:9.

Let the shares of two brothers are 10x and 9x respectively. So, the larger share is 10x.

It is given that the largest share was Gh¢500.00.

10x=500

x=\dfrac{500}{10}

x=50

Now, the total amount shared between them is:

Total=10x+9x

Total=19x

Total=19(50)

Total=950

Therefore, the total amount shared between them is Gh¢950.00.

Which graph shows the solution to the inequality -3x-7x<20
hjlf
A graph of this inequality would be a number line, with the number -2 circled (not filled in), and the number line to the right of -2 shaded.

To solve this, you will combine like terms first:

-3x-7x < 20
-10x < 20

Divide both sides by -10:
-10x/-10 < 20/-10

When you divide an inequality by a negative number, you flip the inequality symbol:

x > -2
