Sum of 8 and 4 (8+4=12) is 12 Difference of 8 and 4 (8-4=4) is 4 So 12/4 is 3
8 & 12
The two numbers are 10 and 2
10 and 4
(8*4) + (8-4) = 32 + 4 = 36 ^ ^ sum ^ product and difference
20/2 = 10 4/2 = 2 10 - 2 = 8 10 + 2 = 12 12 - 8 = 4 12 + 8 = 20
Okay... your sum is 3/4-2/5. First make both fractions the same so... 3/4 = 12/20 and 2/5 = 8/20 Now you have the sum 12/20 - 8/20 which is 4/20. 4/20 simplifies to 1/5
3 & 7? Sum 10, difference 4 so ratio 5:2 or 1 & 21? Sum = 22, difference 20 so ratio 11:10
Two numbers with a sum of 4 and a difference of 9 are -6.5 and 2.5.
