Addition is the first step for two reasons.
1) the Order of Operations requires you do operations in parentheses first
2) the division cannot be performed until you know what you're dividing

It should be 40 percent.

You can think of it as starting with 100 as in 100 dollars or 100 tic tacs

If you take away 25%, you take away 25 tic tacs and now you only have 75.

From your 75, you take away 20% which is equal to 15. 75- 15=60

If you look at the end result of 60, you can see that that is 100 - 40 so 40% of the total was taken off

Evaluate 48/6-10/3 please and thank you :)))
vodomira [7]

Answer:

14/3

Step-by-step explanation:

Simplify the following:

48/6 - 10/3

Hint: | Reduce 48/6 to lowest terms. Start by finding the GCD of 48 and 6.

The gcd of 48 and 6 is 6, so 48/6 = (6×8)/(6×1) = 6/6×8 = 8:

8 - 10/3

Hint: | Put the fractions in 8 - 10/3 over a common denominator.

Put 8 - 10/3 over the common denominator 3. 8 - 10/3 = (3×8)/3 - 10/3:

(3×8)/3 - 10/3

Hint: | Multiply 3 and 8 together.

3×8 = 24:

24/3 - 10/3

Hint: | Subtract the fractions over a common denominator to a single fraction.

24/3 - 10/3 = (24 - 10)/3:

(24 - 10)/3

Hint: | Subtract 10 from 24.
