Given expression is, 83.04 x 2.01 x 2.1The multiplication value without decimal point = 8304 x 201 x 2 = 3338208Sum of the number of decimal places in the given numbers = 2 + 2 + 1 = 5Now, in the product, the decimal point is marked off to obtain as many places of decimal.Then the answer is 33.38208.
We have to find X such that 4/5 < X < 6/7Converting each fraction into decimal form, we get:4/5 = 0.86/7 = 0.85We have to find the fraction which is greater than 0.8 and less than 0.85.Now,2/3 = 0.663/4 = 0.755/6 = 0.8310/11 = 0.91Clearly, 0.83 lies between 0.8 and 0.85.Required fraction is 5/6
