Answers

Answer 1
Answer: Rules in adding fractions:

1) Make sure that they have common denominator.
5/10 + 3/10

2) Since both fraction have a denominator of 10, add the numerator and place the sum above the denominator

5/10 + 3/10 = (5 + 3)/10 = 8/10

3) Simplify the fraction
8/10 can still be simplified into 4/5

8 ÷ 2 = 4
10 ÷ 2 = 5

5/10 + 3/10 = 4/5

PLEASE HELP!! Angelo and Jimmy went shopping. Angelo had a. dollars in his wallet. He spent 1/3 of that money on new jeans. Jimmy had j. dollars in his wallet. He spent 1/2 of that money on a new jacket. Jimmy had more money left than Angelo. Which expression shows the difference between the amounts of money, in dollars, that each boy had left.

Answers

Okay, so Angelo had a dollars and spent 1/3 of that. So he spent 1/3a

Then, the amount he has left can be denoted as: (a - 1/3a)


Jimmy had j dollars and spent 1/2 of it:

So the amount he has left can be denoted as (j - 1/2j)


Since jimmy had more money left, you would subtract the amount angelo has from the amount that jimmy has left.

So: (j - 1/2j) - (a - 1/3a).

X +5+11x=12x+Y It says find the value of y that makes each equation true for all values of

Answers

x + 5 + 11x = 12x + y

Simplify: 12x + 5 = 12x + y (We are adding x and 11x on the left side)

Subtract 12x from each side makes each zero.

5 = y

So we can plug in and test. I'm picking two random numbers to plug in for x. 10, and 82

x = 10, y = 5
10 + 5 + 11(10) = 12(10) + 5
125 = 125

x = 82, y = 5
82 + 5 + 11(82) = 12(82) + 5
989 = 989

So we verified y = 5

Is 11/12 greater than 4/8

Answers

No. 4/8 is greater than 11/12
 
11/12 because it is more than 1/2 (which is what 4/8 simplifies to!)
