Let's look at each pair and change it so the first one in the pair will be what the second one will be converted to.
8,600 mg = 86,000 mg; So now, the first one is not equivalent.
2,500 g = 250,000 g; Not that one either.
3.4 kg = 3.4 kg; This one is correct. We can check by checking the last pair.
480 g = .0048 g; Nope.
So 3.4 kg, 3400 g would be the correct answer.
Instead of subtracting 10, you can add negative 10
15/20 in it's simplest form is 3/4. You have to divide by 5. 15 divided by 5 is 3 and 20 divided by 5 is 4. Hope i helped. Have a nice day.
20/28 = 5/7
Step-by-step explanation:
Step 1 :
Total number of students in the algebra class is 28
Given that the number of students who play neither sport = 8
Step 2 :
Probability that a student randomly chosen does not play any sport is obtained by number of students who play neither sport/ total number of students
Hence probability is 8/28
Step 3 :
The probability that a student randomly chosen plays either basketball or base ball = 1 - 8/28 = 20/28 = 5/7
Answer:
If I did it right it's 12
Step-by-step explanation:
(+9) - (-4) - (+1)= 9-(-4)(+1)
=12
hope this helps, good luck!
