I need help! I forgot how to do this!! Please help!

First change the mixed fraction into an improper fraction
7 1/2 = 15/2
Next, change multiply 2 to both numerator and denominator
15 x 2 = 30
2 x 2 = 4
30/4
Each piece needs 3/4 of an inch. Divide 30 with 3
30/3 = 10
c) 10 pieces is your answer
hope this helps
namely how many times does 3/4 go into 7½.
let's first off convert the mixed fraction to an improper one, and then divide.
[tex] \bf \stackrel{mixed}{7\frac{1}{2}}\implies \cfrac{7\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{15}{2}}\\\\
-------------------------------\\\\
\cfrac{15}{2}\div \cfrac{3}{4}\implies \cfrac{15}{2}\cdot \cfrac{4}{3}\implies \cfrac{15}{3}\cdot \cfrac{4}{2}\implies \cfrac{5}{1}\cdot \cfrac{2}{1}\implies 10 [/tex]
