Question

How many complete pieces of ribbon 7/8cm long can be cut from a roll of ribbin that is 149 cm long

Answer 1

129 to 130 pieces is the answer

Answer 2

$\frac{1192}{7}$
Convert 149 to a fraction ($\frac{149}{1}$). 
To divide by a fraction, use the inverse or reciprocal (switch the numerator and denimoninator).
The reciprocal of $\frac{7}{8} [tex] is [tex] \frac{8}{7}$. 
So, multiply those two fractions together (149 x 8 = 1192) (1 x 7 = 7) to get $\frac{1192}{7}$
