Numerical expressions contain numbers, while algebraic expressions contain variables and numbers.
<u>Numerical Expression</u>
"Difference" indicates that we'll be subtracting 13 from 48.
48 - 13 = 35
<u>Algebraic Expression</u>
Variables represent the unknown number, in this case the difference between 48 and 13. Let d represent the difference between the two.
48 - 13 = d
35 = d
Answer: the answer is 10%
Step-by-step explanation: 1/10. You have to get the denominator to 100 so, you would x10 the debonair. You do the same to the top and get 10/100. So, 10%
Answer:
1/2 x 1/2= 2/4
Step-by-step explanation:
Answer:
Let’s use 2 methods to do this:
First, let’s try cross multiplying:
3/4=x/20
2/5=x/20
20 times 3 = 60
60 divided by 4 is 15, so 3/4 = 15/20
20 times 2 = 40
40 divided by 5 is 8, so 2/5 = 8/20
The next method:
What time 4 equals to 20? What times 5 equals to 20?
4 times FIVE equals to 20
For the fraction of 3/4, multiply the numerator and the denominator by five to get your answer of 15/20.
5 times FOUR equals to 20
For the fraction of 2/5, multiply the numerator and the denominator by four to get your answer of 8/20.
