Whole numbers, integers, fractions, terminating decimals and repeating decimals are all rational numbers.
Think of it like this, if there are 13 cards numbered 1-13 and you need to find the probability of pulling a multiple of 3.
Then start by laying out all your options.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13
Then find all of the multiples of 3
3, 6, 9, 12
There are 4 multiples of 3 out of all of the cards so you have a 4 out of 13 chance to pull a card with a multiple of 3 on it.
Answer = 4/13
Answer:
Second term
Common factor
Step-by-step explanation:
How can you use ratios and rates to solve problems? Compare ratios and rates by finding equivalent ratios and rates with a common second term. Make predictions by finding a common factor and multiplying by it.
Answer:
x = 11/7
Step-by-step explanation:
x - 2/7 = 9/7
x = 9/7 + 2/7
x = 11/7
