subtract the following mixed numbers 4 3/6 - 2 1/3
Answers
Answer:
13/6 or 2 1/6
Step-by-step explanation:
In order to solve this, we have to make the denominators equal
To do that, we will need to multiply 1/3 by 2/2 which will get us 2/6
Now that we have like denominators we can convert the mixed fractions to improper fractions:
4 3/6 ---> 27/6
2 2/6 ---> 14/6
Now we can comfortably subtract the two values and simplify if needed
27/6-14/6= 13/6
So:
4 3/6 - 2 1/3 = 13/6 or 2 1/6

The value of a house increased by 6%.
The house then had a value of £265000.
Work out the value of the house before the increase
Answers
+ 6% = x (1 + 6%) = x 1,06
with V = value before the increase
V x 1,06 = 265,000
so V = 265,000 : 1,06 = 250,000
The value of the house before the growth in its value was £250,000.
What do we mean by growth?We know that the value of most of the things in this world changes from time to time. When the value of an article is increased, we say that there's a growth in its value.
Growth is determined by the formula,
V = V₀(1+r), where V is the final price, V₀ is the initial price and r is the rate.
How do we solve the given question?We are told that the value of a house increased by 6%, reaching £265,000. We are asked to calculate its initial value.
Since the value has increased, we will use the formula for growth,
with V = £265,000, r = 6%, and V₀ is to be determined.
The formula is: V = V₀(1+r)
or, V₀ = V/(1+r) = 265000/(1 + 6%) = 265000/(1 + 6/100) = 265000/(106/100)
or V₀ = 265000*100/106 = 250000
∴ The initial value of the house is £250,000.

what is the value of x in the equation 0.3x = 0.2 - 0.2x?
Answers
Hey there!
0.3x=0.2−0.2x
Step 1: Simplify both sides of the equation.
0.3x=0.2−0.2x
0.3x=0.2+−0.2x
0.3x=−0.2x+0.2
Step 2: Add 0.2x to both sides.
0.3x+0.2x=−0.2x+0.2+0.2x
0.5x=0.2
Step 3: Divide both sides by 0.5.
0.5x/0.5=0.2/0.5
x=0.4
Therefore, x = 0.4
