Can you write an equivalent fraction for 5/9 and 1/10 using the least common denominator?

Yes

Step-by-step explanation:  

Rewriting input as fractions if necessary:

5/9, 1/10

For the denominators (9, 10) the least common multiple (LCM) is 90.

LCM(9, 10)

Therefore, the least common denominator (LCD) is 90.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

5/9=5/9×10/10=50/90

1/10=1/10×9/9=9/90

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
