II. 4/9 × 6
III. 13/10 × 10
IV. 2/15 × 5
V. 12 × 9/30​

Answer 1

Answer:

i) $\frac{3}{5} *7$    ii) $\frac{4}{9} *6=\frac{8}{3}$    iii) $\frac{13}{10 } *10=13$     iv) $\frac{2}{15} *5=6$     v) $12*\frac{9}{30} =\frac{17}{5}$

Step-by-step explanation:

In context to question asked,

We have to find the product of given fractional numbers with whole numbers.

The simple formula is $\frac{a}{b}*c=\frac{a*c}{b}$.

i) $\frac{3}{5} *7$ = $\frac{3*7}{5}$

         = $\frac{21}{5}$

ii) $\frac{4}{9} *6=\frac{4*6}{9}$

         = $\frac{24}{9}$

         = $\frac{8}{3}$  (∵ dividing by $3$)

iii) $\frac{13}{10 } *10=13$

iv) $\frac{2}{15} *5=\frac{30}{5}$

           = $6$   (∵ dividing by $5$)

v) $12*\frac{9}{30} =\frac{12*9}{30}$

             = $\frac{108}{30}$

             = $\frac{18}{5}$ (∵ dividing by $6$)
