Hi there!
j is 7 times greater than 6.
When j is 7 times greater than a number, we get the following equation:
j / 7 = 6
Multiply both sides by 7.
j = 42
The answer is 25%
(1)
If 64 is 100%, 48 is how much percent:
64 : 100% = 48 : x
x = 100% * 48 : 64
x = 75
(2)
Percent of decrease is:
100% - x = 100% - 75% = 25%
The answer is 25%
D and B are the answers because they are the variables.
We need to find how many 1/4 groups are in 1 1/2.
I work better with decimals, so I'll just convert them into decimals. We're dividing to see how many people we need.
1.5÷0.25
6
So, you'll need 6 runners for the relay race.
Yes, that's quite true. It's also a real number, and a negative number.
Did you have a question to ask ?
