Step-by-step explanation:
17% of x = 5
this means that 17/100 * x = 5
dividing both sides by x
17/100 = 5/x
For this you are adding two fractions together. You always want to make sure they are both improper or normal fractions and that they have a common denominator. To find a common denominator, you look at the denominators and look for a number (The smaller the better) that both can be multiplied by some number to get to. In this case, the common denominator is 10. To make the denominators the same you multiply by one so the value doesn't change. This is done by multiplying the numerator and denominator by the same number that results in the denominator becoming the common denominator.
2 1/2 = 5/2 × 5/5 = 25/10
2/5 × 2/2 = 4/10
When adding, the denominator remains the same and the numerators are added!
25 + 4 = 29
So the answer is 29/10 or 2 9/10 when converted back into a mixed number.

Answer:
Step-by-Step Solution
0.4 = 2/5 as a fraction
To convert the decimal 0.4 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
0.4 = 0.41
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,
0.41 = (0.4 × 10)(1 × 10) = 410.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(4,10) = 2. So,
(4÷2)(10÷2) = 2/5 when reduced to the simplest form.
Answer:
Tip= $25
Step-by-step explanation:
<u>First, we need to round the bill to the nearest tenth.</u>
Bill= 47.84 = 50
<u>Now, we can calculate the tip using the following formula:</u>
Bill proportion= 50% = 0.5
Tip= Bill*tip proportion
Tip= 50*0.5
Tip= $25
On a $50 bill, the tip is $25. The total amount to pay is $75.
