63/4 or 15.75 4 * x = 63 where x is our unknown number x = 63/4 dividing both sides by 4 4 * 63/4 = 63 as the 4's cancel
4 + 63³ =4 + (63 x 63 x 63) = 4 + (250,047) = 250,051
31.5 x 2 = 63 15.75 x 4 = 63
Let the number be x:- x-(25*4) = 63 x-100 = 63 x = 63+100 x = 163
(7/9) x (4/63) = (1/9) x (4/9) = 4/81
