$-\displaystyle\frac{1}{2} :1\frac{3}{4}$

First , convert the mixed number (the fraction we are dividing by in the given maths problem) into an improper fraction .

Multiply the whole part (1) times the denominator (4) and add the numerator . The result is the numerator of our fraction , and the denominator stays the same .

So now our maths problem looks as follows :

$-\displaystyle\frac{1}{2} :\frac{7}{4}$

Now turn the fraction you are dividing by over :

$-\displaystyle\frac{1}{2} *\frac{4}{7}$

Now multiply the numerator of the first fraction times the numerator of the second fraction :

4

Perform the same operation with the denominators :

-4/14

So the result is :

$-\displaystyle\frac{4}{14}$

Since the above fraction is not in it's simplest form , we divide the top and bottom by 2 (a common factor of both 4 and 14) :

$-\displaystyle\frac{2}{7}$

Please help with 2.3. I don’t get it

larisa [96]

The answer to the first question is g. h represents hamburgers. If you take the number of hamburgers and substitute it for h, so 2h= 2 times 36, you get 72. 2 times 50 you get 100. 2 times 49 is 98.

For question 2, h represents hours. The answer to this question is a. 50 is being multiplied by h. So, 50 times 2 is 100. 50 times 3 is 150. 50 times 5 is 250 and so on.

Hope this helped.
