The answer would be 9/20
Step-by-step explanation:
To find this, first note that 3/8 and -3/8 would cancel each other out. So then we would have just two terms to add together. Give them like terms and then add them together.
-4/5 + 5/4
-16/20 + 25/20 = 9/20
Answer:
306.
Step-by-step explanation:
Firstly, we are aware 100% of 680 is obviously 680,
Next, we know half of a 100% is 50% therefore half of 680 is 340.
Then, we know 45% is 5% less than 50%
To find 5% of a number mentally, divide it by 10 as 100÷5=20
680÷20=34
Lastly 50% subtracted by 5%: 340-34=306.
Now we know, 45% of 680 is 306.
