Question

6) IF THE SAME NUMBER IS ADDED TO THE NUMBERS 2,4, 14 AND 22 THEN THE RESULTANT NUMBERS ARE IN PROPORTION .FIND THE NUMBER.
7) FIND A NUMEBR SUCH THAT IF 25,7 AND 7 ARE ADDED TO IT , THE PRODUCT OF THE FIRST AND THIRD RESULTS IS EQUAL TO THE SQUARE OF THE SECOND.
8) WHAT MUST BE ADDED TO THE NUMERATOR AND DENOMINATOR OF THE FRACTION 5/12 TO MAKE IT EQUAL TO 2/3?
9) THE DENOMINATOR OF A FRACTION IS GREATER THAN THE NUMERATOR BY 3. IF 7 IS ADDED TO THE NUMERATOR ,THE FRACTION INCREASES BY UNITY. FIND THE FRACTION.
10) IF THE SAME INTEGER IS ADDED TO THE NUMEBRATOR OF THE FRACTION 2/7 AND SUBTRACTED FROM THE DENOMINATOR ,THE FRACTION BECOMES 2. WHAT IS THE INTEGER?

Answer 1

Step-by-step explanation:

(6) let 'x' as the number to be added

2+x/4+x = (4+x) (14+x)

therefore , (2+x)(22+x)=(4+x)(14+x

44+2x+22x+x 2= 56+4x+14x+X2

24x+44=18x+56

therefore 2 is the number .
