Divide 5600 in the ratio 4 :5:7 <br>

Elis [28]

Answer:

Step-by-step explanation:

So in our case, let assume 'x' as a common factor.

Thus,

4x + 5x + 7x = 5600;

16x = 5600;

x = 5600/16 = 350.

So,

4x= 350*4 =1400;

5x= 350*5 = 1750; &

7x= 350*7 = 2450.

Your answer is, 5600 = 1400+1750+2450 which is in ratio of 4:5:7.

(2/3 - 3/4 × 1/8) ÷ (2/3 - 3/4 + 5/8)

kati45 [8]

<h3>Given:</h3>

$( \frac{2}{3} - \frac{3}{4} \times \frac{1}{8} ) \div ( \frac{2}{3} - \frac{3}{4} + \frac{5}{8} )$

<h3>Solution:</h3>

First, solve the brackets.

First bracket:

$( \frac{2}{3} - \frac{3}{4} \times \frac{1}{8} )$

$= \frac{55}{96}$

Second bracket:

$( \frac{2}{3} - \frac{3}{4} + \frac{5}{8} )$

$= \frac{13}{24}$

Then divide.

$\frac{55}{96} \div \frac{13}{24}$

$= \frac{55}{52} \: or \: 1\frac{3}{52}$
