In a calculator: 1/11 = 0.09090909..... 2/11 = 0.18181818..... 3/11 = 0.27272727..... (Notice: bold numbers are multiples of 9) There is a patern, for each multiple of 1/11 (which is equivalent to the numerator), we get a "0.", followed by the same multiple of 9 as the multiple of 11, displayed as two digits, which are repeated infinitely; We can apply this principle to find the decimal equivalents of the two other fractions as they have the same denominator, so:
For 7/11: We do: 7 * 9 = 63 So: 7/11 = 0.63636363..... (= 0.63 recurring)
For 8/11: 8 * 9 = 72 So: 8/11 = 0.72727272..... (= 0.72 recurring)
