4/5-1/2 answer my question

Mathematics

4/5 - 1/2 =

3/10 in exact form

0.3 in decimal form

When subtracting a fraction, you always have to make sure your denominator/divisor's are the same.

Therefore you would find the Least Common Multiple of 5 and 2

Both would eventually come to 10, multiplying 4/5 by 2 on both the numerator and the denominator

Do the same with 1/2 except you multiply this one by 5 on both the numerator and the denominator.

Your fractions would then be  8/10 and 5/10

Then you subtract

8/10 - 5/10 = 3/10

(The Denominator does not change after all this)

Hope this helps :)

3/10 you cross multiply 5x2=10 so the denominator will be 10 and then cross multiply the numberators by the different denominator make sense? so 5x 1=5 and that mean 1/2=5/10 and 4/5=8/10 and the final answer when u subtract is 3/10 makes sense? u know what i mean jelly bean?

I have a two digit number the sum of the digits is 12 the first digit is 4 Less Than 3 times the second what is my number​
nignag [31]

Answer:

84

Step-by-step explanation:

Let the first digit = x

Let the second digit =y

x + y = 12

x + 4 = 3*y

===========

From the second equation, we learn that x = 3y - 4

Put that into the first equation.

3y - 4 + y = 12          Combine the left side

4y - 4 = 12                Add 4 to both sides

4y = 16                     Divide by 4

4y/4 = 16/4        

y = 4  

=================

x + 4 = 12

x + 4 - 4 = 12-4

x = 8

So the number is 84
