Yes, -789 is a rational number
Yes, it is.
To any set that contains it! It belongs to {789}, or {789, sqrt(2), pi, -3/7}, or {789, bananas, France, cold} or all whole numbers between -43 and 5003, or multiples of 3, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
1, 3, 263, 789.
1.578 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, since it is a decimal fraction, there is not another simpler decimal form. Its equivalent, in rational form, is 1578/1000 which simplifies to 789/500..
Yes, -789 is a rational number
Yes, it is.
Because it can be expreesed as ratio of two integers: 789 and 1000.
To any set that contains it! It belongs to {789}, or {789, sqrt(2), pi, -3/7}, or {789, bananas, France, cold} or all whole numbers between -43 and 5003, or multiples of 3, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
789 x 789 = 622521.
Zero out the Y to find X 3X - 2(0) = -789 3X = -789 X = -263 ------------- now to check you need to find Y, so zero out X 3(0) - 2Y = -789 - 2Y = - 789 Y = 394.5 0r 394 and 1/2 convert to fraction = 789/2 ------------ check 3(-263) - 2(789/2) = -789 -789 - 2(789/2) = -789 cancel one 2 and multiply through by that 2 -1578 + 789 = - 789 -789 = - 789 checks
