Question

Two numbers are in the ratio 8:3. If sum of the numbers is 143, find the numbers.

Answer 1

Answer:

104,39

Step-by-step explanation:

8x+3x=143

11x=143

X=143/11

X=13

8x=8(13)=104

3x=3(13) =39

Answer 2

Answer:

$8 : 3 \\ 8x : 3x \\ \\ 8x + 3x = 143 \\ 11x = 143 \\ x = \frac{ \cancel{ 143}_{ \: \: 13} }{ \cancel{ 11}_{ \: \: 1}} \\ x = \underline{ \underline{ 13}} \\ \\ 8 : 3 \\ 8x : 3x \\ 8(13) : 3(13) \\ \underline{ \underline{ 104 : 39}} \\ \\ 104 + 39 = 143$
