Question

10.Divide 77 into three parts in the ratio of 2 : 4 : 5
​

Answer 1

Answer:

14, 28, and 35

Step-by-step explanation:

2 : 4 : 5= 77

$\\ \tt{}2x + 4x + 5x = 77$

$\\ \tt{}11x = 77$

$\\ \tt{}x = \frac{77}{11}$

$\\ \tt{}x = 7$

===============================

For the first part:

$\\ \tt{} = 2 \times 7$

$\\ \boxed{ \tt{} = 14}$

===============================

For the second part:

$\\ \tt{} = 4 \times 7$

$\\ \boxed{ \tt{} = 28}$

===============================

For the third part:

$\\ \tt{} = 5 \times 7$

$\\ \boxed{ \tt{} = 35}$

===============================

Check to verify:

$\\ \tt{} 14 + 28 + 35= 77$

$\\ \tt{}77 = 77$

===============================

$\overbrace{ \underbrace{ \tt{} \purple{ \: \: Stay \: safe \: and \: God \: bless \: you! \: \: }}}$
