It is 23 because 17+19+21+23 = 80
28 is the answer. if 12 is 15% of a number ,the number is 80. 35% of 80 is 28
No, 80 is a not perfect square.
If 45 = 120% then simply divide 45 by 120, to find 1%, which is 0.375 and then multiply this by 80 to find 80%, which is 30 - or - 1.20X = 45; X = 45/1.20 = 37.5; then 80% of the number is: 37.5 X .80 = 30
It is a rational number because it can be expressed as an improper fraction in the form of -80/1
To get 80 using four number 5s, you can use the following mathematical expression: (5 x 5) + (5 x 5) + (5 - 5) = 80. This equation breaks down to 25 + 25 + 0 = 80. By multiplying two fives to get 25 twice and subtracting 5 from 5 to get 0, you can achieve a total of 80.
4x5=20 20x4=80 come on I'm in yr7 and i knew that straight away
(5+5+5) x5 +5 =80. Cancels to: (15) x5 +5 =80 75 +5 =80 80=80
64 is 80% of 80
Ummmmm this did not help at all! never using this again!
