Question

the product of two numbers is 6/7 . one is 3/4 . find the other . by step by step . I need by step by step only . the first clear answer which I understood will only get brilliantist answer . ​

Answer 1

Answer:

number consists of two digits whose sum is 9. If 27 is added to the number, its digits are interchanged. Which of the given steps is CORRECT to find the number?

Step 1 : Let the units digit be x

Step 2 : Then, ten's digit = (9 - x)

Number = 10 x (9 - x) + x

90 - 10x + x = (90 - 9x)

Step 3 : Adding 27 to the number 90 - 9x, we get 117 - 9x

Step 4 : Number with digits interchanged is 10x + (9 - x) = 9x + 9

Step 5 : 117 - 9x = 9x + 9

Step 6 : Therefore unit's digit = 6 and ten's digit = 3

Step 7 : Hence the number = 36.

Answer 2

Answer:

8/7

Step-by-step explanation:

3/4 * x = 6/7

x=(6/7) / (3/4)

x=6*4 / 7*3

x=24/21

x=8/7
