We have to find, the value of 4/7 of 560 - 5/8 of 400.4/7 x 560 - 5/8 x 400 = (4 x 80) - (5 x 50) = 320 - 250 = 70Hence, four-seventh of 560 is greater than five-eighth of 400 by 70.
Given expression is, 0.004 x 0.04 x 0.4 x 0.0004The multiplication value without decimal point = 4 x 4 x 4 x 4 = 256Sum of the number of decimal places in the given numbers = 3 + 2 + 1 + 4 = 10Now, in the product, the decimal point is marked off to obtain as many places of decimal.Then the answer is 0.0000000256.
