(292÷73=4)
(203÷7=29) the remaining number's 4 *29/145.
29*5=145 so 4/5 is the answer

More than to take the approximations it could be a better way to remove the decimal point to get the nearest answer.
And proceed on.
And proceed on.

If numerator and denominator of a fraction contain the same number of decimal places, then we remove the decimal sign.

I don't understand why approximations have been allowed when the = is straight. or is it that as the total number of decimal places moved top and bottom is 6 and as long as this is equal, this is ok?
