Question

Can someone help me with this problem it’s question number 6

Answer 1

Answer:

$\frac{57}{16}$ lb

Step-by-step explanation:

$\frac{7}{8} +1\frac{3}{4} +\frac{15}{16}$

Change the mixed fraction into an improper fraction,

$\frac{7}{8} +\frac{7}{4} +\frac{15}{16}$

Now convert the denominator to 16 (since 8 and 4 are factors of 16)

And remember that what you do to the denominator, you must do the same to the numerator!

$\frac{14}{16} +\frac{28}{16} +\frac{15}{16}$

Now that we have all fractions with the same denominator, we can simply add all the numerators together,

= $\frac{57}{16}$

It cannot be simplified any further, so this is your answer!

Hope this helped!!
