Question

find a product of 
a) 7 1/2+2 4/15
      and
b)3 6/7 x 4 2/3

Answer 1

a) $7 \frac{1}{2} + 2 \frac{4}{15}$

⇒$\frac{15}{2} + \frac{34}{15}$

Now taking the LCM, LCM=30

⇒$\frac{15×15+34×2}{30}$

⇒$\frac{293}{30}$
Now converting into mixed fractions:

⇒$9 \frac{23}{30}$

b) $3 \frac{6}{7}× 4 \frac{2}{3}$

⇒$\frac{27}{7} × \frac{14}{3}$

⇒18
