The calculator will simplify the ratio A : B if possible. Otherwise the calculator finds an equivalent ratio by multiplying each of A and B by 2 to create values for C and D. In engineering, fractions are widely used to describe the size of components such as pipes and bolts. The most common fractional and decimal equivalents are listed below. 64 th A 1.75 prescription is an intermediate value between 1.50 and 2.00. A prescription of 1.50 means slightly lesser refractive error compared to 1.75, while a 2.00 prescription indicates a higher refractive error. In simpler terms, with a 1.50, your vision impairment might be a tad less pronounced than at 1.75, whereas with a 2.00, it might be more pronounced. Cylindrical correction (CYL): Cylindrical correction is the second number and is only on prescriptions for people with astigmatism. The first multiple they all share is 12, so this is the least common multiple. To complete an addition (or subtraction) problem, multiply the numerators and denominators of each fraction in the problem by whatever value will make the denominators 12, then add the numerators. EX:

The strength of all reading glasses is measured in dioptre, with units increasing by 0.25 dioptre depending on the power of the lens. Conversion a mixed number 1 1 / 5 to a improper fraction: 1 1/5 = 1 1 / 5 = 1 · 5 + 1 / 5 = 5 + 1 / 5 = 6 / 5 Proper fraction button is used to change a number of the form of 9/5 to the form of 1 4/5. A proper fraction is a fraction where the numerator (top number) is less than the denominator (bottom number). While most frames can accommodate a 1.75 prescription, thinner and lighter high-index lenses may be recommended for those seeking a sleeker appearance, especially if choosing larger frames.The technical term for this condition is presbyopia, a natural, age-related change in the lens of the eye which makes it more difficult to focus on smaller print and close-up objects. An alternative method for finding a common denominator is to determine the least common multiple (LCM) for the denominators, then add or subtract the numerators as one would an integer. Using the least common multiple can be more efficient and is more likely to result in a fraction in simplified form. In the example above, the denominators were 4, 6, and 2. The least common multiple is the first shared multiple of these three numbers. Multiples of 2: 2, 4, 6, 8 10, 12 One meter is a length measurement and equals approximately 3.28 feet. One foot equals 12 inches exactly. If you need to be super precise, you can use one meter = 3.2808398950131 feet. Once this is very close to 3.28 feet, you will almost always want Wearing corrective lenses won’t improve or worsen your natural eyesight. They merely adjust the light entering your eyes to provide clearer vision. However, not wearing them when needed can lead to eye strain or headaches. Do you have problems with simplifying fractions? The best way to solve this is by finding the GCF (greatest common factor) of the numerator and denominator and dividing both of them by GCF.

Step 3: Reduce the fraction. Find the Greatest Common Factor (GCF) of the numerator and denominator and divide both numerator and denominator by the GCF.

How to convert from decimal to percent

For the repeating decimal 0.857142857142857142..... where the 857142 repeats forever, enter 0.857142 and since the 857142 are the 6 trailing decimal places that repeat, enter 6 for decimal places to repeat.

Beyond this, converting fractions into decimals requires the operation of long division. Decimals (decimal numbers) enter with a decimal point . and they are automatically converted to fractions - i.e. 1.45.

How to convert meters to feet and inches step-by-step

Similarly, fractions with denominators that are powers of 10 (or can be converted to powers of 10) can be translated to decimal form using the same principles. Take the fraction 1 Step 1: Make a fraction with the decimal number as the numerator (top number) and a 1 as the denominator (bottom number). The car's fuel was ¾ full at the beginning of the week. At the end of the week, there was ⅛ of a tank left. a. Did the car use more or less than ½ of a fuel tank? How do you know? b. How much more or less than ½ of a tank did it use? Show your work using
