|
Answer» :-55% of 640 cm = 352.x = 55%.Given :-x% of 640 cm = 352.To find :-The value of x.Step-by-step EXPLANATION :-Lets find the value of x.Lets also ignore the units for our convenience. We can add them in our answer later.On converting x% to fraction,Cutting off the zeroes,Reducing the numbers,On multiplying,Transposing 5 from LHS to RHS, CHANGING it's sign, On multiplying,Transposing 32 from LHS to RHS, changing it's sign,Dividing 1760 by 32,Therefore, 55% of 640 cm = 352.________________________________Verification :-To check our answer, lets put 55% (The value of x) instead of x and see whether LHS = RHS or not.Doing so, we get :-LHSConverting 55% into fraction,Cutting off the zeroes,Reducing the numbers,Reducing the numbers again, can be written as 11, so :-On multiplying,RHSSince LHS = RHS,Hence verified!________________________________ |
