Step-by-step explanation:
We need to find, how many 1/3s are in 1 2/3 the hexagon represents 1 whole.
In order to find that value, we need to divide 1 2/3 by 1/3.
Let us first convert 1 2/3 into improper fraction first.
1 2/3 = (1*3+2)/3 = 5/3.
Therefore,
5/3 ÷ 1/3.
Changing division sign into multiplication and flipping the second fraction, we get
5/3 × 3/1
3's cross out from top and bottom, we get
= 5.
<h3>Therefore, there are 5 times of 1/3s in 1 2/3.</h3>
Answer:
B
Step-by-step explanation:
(f+g)(x) means add f(x) and g(x) together:
(x/2)-2 + 2x^2 +x -3
collect all the like terms:
2x^2
(x/2) + x = 3/2x (explanation below)
-2 -3 = -5
x/2 + x can be turned to 1x/2 + 2/2x (2/2 = 1, so when you simplify it to 1x, it is still x)
