What is 21 30 in simplest form?
To simplify the fraction 21/30, we need to find the greatest common factor (GCF) of both numbers, which is 3. Dividing both the numerator and denominator by 3 gives us 7/10. Therefore, 21/30 simplified to its simplest form is 7/10.
What number can go into both 14 and 49?
14 = 2*7 49 = 7*7 So 1, -1, 7, -7 all go into both 14 and 49.
Is 21 over 30 in its lowest terms 7 over 10?
Yes, because 3 is the only number that both can be divided by to further reduce both sides. 21/3 = 7, 30/3= 10 so, 21/30 = 7/10

What two numbers multiply to 1600 and add to 60?
Let the numbers be x and y, then x + y = 60 (which yields y = 60 - x) xy = 1600 (replace y with 60 - x) x(60 - x) = 1600 60x - x2 = 1600 (multiply by -1 to both sides) x2 - 60x = -1600 (add 302 to both sides to complete the square) x2 - 60x + 302 = -1600 + 900 (x - 30)2 = -700 (take the square root of both sides) x - 30 = ± √-700 (add 30 to both sides and write -700 = (100)(7)(-1)) x = 30 ± (√100)(√7)(√-1) x = 30 ± (10√7)i So, x = 30 + (10√7)i or x = 30 - (10√7)i thus, y = 60 - [30 + (10√7)i] or y = 60 - [30 - (10√7)i ] y = 30 - (10√7)i or y = 30 + (10√7)i Therefore, [30 + (10√7)i] + [30 - (10√7)i] = 60 [30 + (10√7)i] [30 - (10√7)i] = 1600 Check:
